<p>If you look at each component's JS file, you'll notice that no code was necessary.</p>

<p>The action is pushed down to the component and sent back up to the controller primarily through the template itself!</p>

<button {{action (action buttonClick)}}>{{label}}</button>

templates.components.my-top-level-component.hbs

<div class="top-level-component">
		<h4>Top Level Component</h4>
		<div style="border: 1px solid red; padding: 10px">
    	<h5>Nested Component</h5>
      {{#each buttonArray as |button|}}
