title: Ember action or this.get works only once
body: <p>I have this index controller.</p>
  
  <pre><code>import Ember from 'ember';
  
  export default Ember.Controller.extend({
      actions: {
          reload() {
              console.log('click on button reload');
              this.get('doReload');
          }
      },
      doReload: Ember.computed(function() {
          console.log('do reload method');
          // ajax action will be here.
      }),
  });
  </code></pre>
  
  <p>And this is button in the template.</p>
  
  <pre><code>&lt;button type="button" class="btn btn-secondary btn-sm" {{action 'reload'}}&gt;Reload&lt;/button&gt;
  </code></pre>
  
  <p>When I click on the button for the first time, <code>console.log()</code> contain 2 line of messages correctly.</p>
  
  <blockquote>
    <p>click on button reload<br>
    do reload method</p>
  </blockquote>
  
  <p>But when I click on the button for second time or more, <code>console.log()</code> contain contain only one line. It doesn't call <code>doReload</code> again.</p>
  
  <blockquote>
    <p>click on button reload</p>
  </blockquote>
  
  <p>How to make this.get work every time I click on the action button?</p>
