❔ Being able to change Navigation title of a page at runtime

I am trying to write some code that will change the navigation title of a page during runtime. I am trying to implement the solution found on this page:https://stackoverflow.com/questions/45834558/how-to-dynamically-change-the-navigation-bar-title-when-contentview-changes However, it is not working for me. Could I get a second pair of eyes and check to see what I am missing? XAML Code:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:viewModels="clr-namespace:The_Juice.ViewModel"
             x:Class="The_Juice.SubclubMenu"
             x:Name="_self"
             x:DataType="viewModels:BlendDescriptionModel"
             Title="{Binding Path=Content.Title, Source={x:Reference _self}}">
    <ScrollView>
        <VerticalStackLayout>
            <Image Source="{Binding  ClubImage}"></Image>
            <Label Text="{Binding ClubName}"></Label>
            <Label Text="Ingredients:"></Label>
            <Label Text="{Binding ClubIngredients}"></Label>
            <Label Text="{Binding ClubDescription}"></Label>
            <Button Text="Sign Up" x:Name="SignUpButton"></Button>
        </VerticalStackLayout>
    </ScrollView>
</ContentPage>

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:viewModels="clr-namespace:The_Juice.ViewModel"
             x:Class="The_Juice.SubclubMenu"
             x:Name="_self"
             x:DataType="viewModels:BlendDescriptionModel"
             Title="{Binding Path=Content.Title, Source={x:Reference _self}}">
    <ScrollView>
        <VerticalStackLayout>
            <Image Source="{Binding  ClubImage}"></Image>
            <Label Text="{Binding ClubName}"></Label>
            <Label Text="Ingredients:"></Label>
            <Label Text="{Binding ClubIngredients}"></Label>
            <Label Text="{Binding ClubDescription}"></Label>
            <Button Text="Sign Up" x:Name="SignUpButton"></Button>
        </VerticalStackLayout>
    </ScrollView>
</ContentPage>

C# Code

namespace The_Juice;
using The_Juice.ViewModel;

public partial class SubclubMenu : ContentPage{
    BlendDescriptionModel SelectedDescription;
    public static readonly BindableProperty TitleProperty = BindableProperty.Create("Title",
        typeof(string),
        typeof(SubclubMenu),
        defaultValue: null,
        defaultBindingMode: BindingMode.OneWayToSource);
    public string Title{
        get => (string)GetValue(TitleProperty);
        set => SetValue(TitleProperty, value);
    }
    public SubclubMenu(BlendDescriptionModel Value{
        InitializeComponent();
        SelectedDescription = Value;
        Title = SelectedDescription.ClubName;

    }
}

namespace The_Juice;
using The_Juice.ViewModel;

public partial class SubclubMenu : ContentPage{
    BlendDescriptionModel SelectedDescription;
    public static readonly BindableProperty TitleProperty = BindableProperty.Create("Title",
        typeof(string),
        typeof(SubclubMenu),
        defaultValue: null,
        defaultBindingMode: BindingMode.OneWayToSource);
    public string Title{
        get => (string)GetValue(TitleProperty);
        set => SetValue(TitleProperty, value);
    }
    public SubclubMenu(BlendDescriptionModel Value{
        InitializeComponent();
        SelectedDescription = Value;
        Title = SelectedDescription.ClubName;

    }
}
