Calling method on Child Component - Composition API

Question

I have a parent component where I need to call a method that exists in one of its child components:

<template>
  <div>
    <button @click="callChildMethod">
    <child-component ref="child" />
  </div>
</template>
<script>
  setup(props) {
    const child = ref(null)
    const callChildMethod = () = {
      child.doSomething()
    }

    return {
      child,
      callChildMethod
    }
  }
</script>

The child component contains the doSomething method:

const doSomething = () => { console.log('calling method....') }

Since I'm using the VueJS3 and the Composition API, my approach was to use a template ref to call the method in the child component. Obviously is not working but I can't see what I'm missing. Does someone have a clue about this one? Thanks in advance

You're missing the value field in your ref, it should be :

 const callChildMethod = () = {
  child.value.doSomething()
}
