You suppose we have this html tag in parent component which i want to observe that from child using v-model:

<textarea v-model="email"></textarea>

like with that:

<template>
    <textarea v-model="caption"></textarea>
    <print :caption="caption"/>
</template>

<script>
import print from "./print";

export default {
    data() {
        return {
            caption: ''
        }
    },
    components: {
        print
    }
}
</script>

print child component:

<template>
    <p v-html="caption"></p>
</template>

<script>

export default {
    props:{
      caption : String
    },
    mounted() {
        this.$emit('caption', this.$el.innerText)
    }
}
</script>

now after each typing in parent component how can i observe from child parent and show in p tag? this code is not correct and i can't resolve problem?
