Custom field dynamic query

Here I have to create a custom field where I have to show suggestion by type [ char and variable name. I want to make it generic where user should pass the query builder and suggest according to the user enter value. 
DynamicVairable::make('dynamic_varibale')
  ->modifyingQuery(function () {
      return Notification::query();
  })
DynamicVairable::make('dynamic_varibale')
  ->modifyingQuery(function () {
      return Notification::query();
  })
But I don't know how to make it dynamic 
class DynamicVairable extends Field
{
    protected string $view = 'forms.components.variable-field';

    public string $text = '';


    public Builder |\Closure $modifyingQuery;

    public function modifyingQuery(Builder | \Closure $modifyingQuery): static
    {
        $this->modifyingQuery = $modifyingQuery;

        return $this;
    }

    public function getModifyingQuery()
    {
        if($this->modifyingQuery instanceof \Closure) {
            return ($this->modifyingQuery)();
        }
        return $this->modifyingQuery;
    }

    public function searchVariable(string $value)
    {
        $this->getModifyingQuery()->where('variable', 'like', '%'.$value.'%')->get();
    }
}
class DynamicVairable extends Field
{
    protected string $view = 'forms.components.variable-field';

    public string $text = '';


    public Builder |\Closure $modifyingQuery;

    public function modifyingQuery(Builder | \Closure $modifyingQuery): static
    {
        $this->modifyingQuery = $modifyingQuery;

        return $this;
    }

    public function getModifyingQuery()
    {
        if($this->modifyingQuery instanceof \Closure) {
            return ($this->modifyingQuery)();
        }
        return $this->modifyingQuery;
    }

    public function searchVariable(string $value)
    {
        $this->getModifyingQuery()->where('variable', 'like', '%'.$value.'%')->get();
    }
}
This is my custom field 
<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    <div x-data="{ state: $wire.$entangle('{{ $getStatePath() }}') }">
      <input x-model="state">
    </div>
</x-dynamic-component>
<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    <div x-data="{ state: $wire.$entangle('{{ $getStatePath() }}') }">
      <input x-model="state">
    </div>
</x-dynamic-component>
Please suggest some idea I tried with livewire component but from field class I'm not able to pass query builder

for Closures add the trait use EvaluatesClosures; and: 
public function getModifyingQuery()
{
    $this->evaluate($this->modifyingQuery);
}
public function getModifyingQuery()
{
    $this->evaluate($this->modifyingQuery);
}
in your livewire version where are calling searchVariable? I think you need an action somehow to trigger it?

@Lara Zeus Thank you for replying. In livewire version. 
<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    <div x-data="{ state: $wire.$entangle('{{ $getStatePath() }}') }">
       <livewire:live-varibale x-model="state" :field="$field->getModifyingQuery()"/>
        <input x-model="state">
    </div>
<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    <div x-data="{ state: $wire.$entangle('{{ $getStatePath() }}') }">
       <livewire:live-varibale x-model="state" :field="$field->getModifyingQuery()"/>
        <input x-model="state">

This is my custom field blade file. I want to pass query builder to livewire. But livewire says prototype issue. 
<?php
class LiveMention extends Component
{
    public Builder $query;
    public $variables = [];
    public $showVariables = false;
    public function mount($query) {
        $this->query = $query;
    }
    public function searchVariables(string $value)
    {
        $searchString = Str::remove('[', $value);
        $this->showVariables = strlen($value) > 0;
        $this->variables = $this->query
            ->where('title', 'like','%'.$searchString.'%')
            ->get()->map(function($variable) {
            return [
                'id' => $variable->id,
                'title' => $variable->title,
            ];
        });
    }

    public function triggerVariable($variableName)
    {
      // Emit the selected variable back to JavaScript
      $this->dispatch('triggerVariable', ['title' => $variableName]);
    }

    public function render()
    {
        return view('livewire.live-varibale');
    }
}
<?php
class LiveMention extends Component

    public Builder $query;
    public $variables = [];

    }
    public function searchVariables(string $value)
    {
        $searchString = Str::remove('[', $value);
        $this->showVariables = strlen($value) > 0;
        $this->variables = $this->query
            ->where('title', 'like','%'.$searchString.'%')
            ->get()->map(function($variable) {
            return [
                'id' => $variable->id,
                'title' => $variable->title,

I want to call searchVariables on change the input field ISSUE: 1. From blade file unable to pass query on livewire class. 2. If I not use livewire then how to call searchVaribales method of blade class from custom field blade file. Note: What I try to do is, Create custom field where I have to add dynamic variables. Anyone have any idea💡
