VueJs: Touch after modifying selection value in child component

Question

I'm using VueJs and I have this child component in my parent component. When the selection of the child component changes, I need to trigger a function in the parent component.

Subcomponent:

watch: {
    selectCoin() {
      this.$emit("currencyType", this.selectCoin["title"]);
    }
}

The child component I use inside the parent component:

<app-select-coin
  @coin="body.value = $event"
  @currencyType="body.currencyType = $event"
  :data="body"
/>

When the child component responds to the $emit of the parent component, I need to call this method:

methods :{
   myFunction() {

   }
}

Answer 1

I successfully accomplished this by adding a function in the "v-on" of @currencyType and passing it the value received from the child component as a parameter.

<app-select-coin
  @coin="body.value = $event"
  @currencyType="myFunction(body.currencyType = $event)"
  :data="body"
/>

methods :{
   myFunction(ct) {

   }
}
