How can I write the {{each}} view to the childViews in the parent view?

I'm doing some animations where I'm catching events on the parent view and want to animate my childViews in a certain order. So I've ended up with something like this:

views/index.js

import Ember from 'ember';

export default Ember.View.extend({
  click: function(){
    console.log(this.childViews) // undefined :'(
  }
});

views/post.js

import Ember from 'ember';

export default Ember.View.extend({});

My template:

{{#each post in content itemViewClass="post"}}
  <img {{bind-attr src=post.image}}">
{{/each}}

I don't quite understand how I can access the access the post views from my index view.
