Info from Children to Parent

Hi guys sorry for my noobish question, i came from svelte where to pass something from the children to the parent (in this case a function), in the children i do

export let handler = ()=>{}

export let handler = ()=>{}

assign that to an click event

<div on:click={handler}></div>

<div on:click={handler}></div>

and in the parent i can just call the handler and thats it. How i can do the same on solid?, i try to do the same approach with an onClick={handler} or onClick={[handler]} on the children and try to print a simple log on the parent without luck.

in solid js customevents are just props, so create a prop named onClick in the child component then pass the handler to that prop and call the prop in the child

import { render } from "solid-js/web";
import { createSignal } from "solid-js";

function Child(props) {
  return <button onClick={props.onClick}>Click Me</button>;
}

function Parent() {
  const [count, setCount] = createSignal(1);
  const increment = () => setCount(count() + 1);

  return (
    <>
      {count()}
      <Child onClick={increment} />
    </>
  );
}

render(() => <Parent />, document.getElementById("app")!);

import { render } from "solid-js/web";
import { createSignal } from "solid-js";

function Child(props) {
  return <button onClick={props.onClick}>Click Me</button>;
}

function Parent() {
  const [count, setCount] = createSignal(1);
  const increment = () => setCount(count() + 1);

  return (
    <>
      {count()}
      <Child onClick={increment} />
    </>
  );
}

render(() => <Parent />, document.getElementById("app")!);
