Vuejs - Passing parameter of component to parent(root)

Hi guys, i need a little help com F7Vue.

I am trying to call a function that is in my parent file on my child, in other words, I have a component that needs to access a function that is in the parent.

To better understand, I will put the files below …

My file root(parent)

This my component, i need call my function in parent “successForm”, the question, how?

Use events to pass data to parent:
In child:

this.$root.$emit('someEvent', {foo: 'bar'});

In parent:

this.$root.$on('someEvent', (data) => {
  console.log(data); // -> {foo: 'bar'}

Problems solved! THanksss!!
