templates.application.hbs

<p>
About this example:
  <ul>
    <li>Native events: e.g. <code>&lt;div onclick=\{{action 'theAction'}}&gt;&lt;/div&gt;</code></li>
    <li>Ember events: e.g. <code>&lt;div \{{action 'theAction'}}&gt;&lt;/div&gt;</code></li>
    <li>Ember events are executed after Native events</li>
    <li>Stopping the bubbling of Native events stops all Ember events</li>
    <li>Stopping the bubbling of Ember events does not stop Native events</li>
    <li>You can play around with <code>x-bar.hbs</code> to have a feel of the sequence</li>
  </ul>
</p>

  View hierarchy: <code>Application Controller => x-bar => x-foo</code>
