I am using Vue.js 2.0 and I am trying to emit an event from `child component`

I am using Vue.js 2.0 and I am trying to emit an event from child component to parent component but it's not working.

You can see my code below:

child component:

<template>
  <button @click="confirmSendMessage">Send</button>
</template>

<script>
  export default {
    methods: {
      confirmSendMessage () {
        this.$emit('confirmed')
      }
    }
</script>

parent component:

<template>
    <ConfirmMessage/>
</template>

<script>
    import ConfirmMessage from './ConfirmMessage'
    export default {
        events: {
           confirmed() {
              console.log('confirmed')
           }
        },
        components: {
            ConfirmMessage
        }
   }
</script>

When I click on the button, nothing appears to me on the Chrome console. I don't know why. Can anybody help me? I am new on Vue JS.

You missed to listen the emitted event. Use v-on to listen to the event:

<!--                               vv -> call method -->
<ConfirmMessage v-on:confirmed="confirmed" />
<!--                  ^^ -> emitted event -->
