Trying to make a custom event, what's wrong?

Question

Vue.js

There is an element on the page on which an attempt was made to hang an event on click and passing a parameter:

<div @click="$root.$emit('item-selected', [item, version])"></div>

In a vue instance not related to this element, trying to process it (the 'mounted' section):

this.$root.$on('item-selected', function (data) {
            console.log(data);
            Loader.Finish();
 });

Does not work. What can be wrong ? Newbie in vue, don't kick too much)
