title: Pass controller action to a component in EmberJS returns undefined
body: <p>I have a controller in EmberJS with an action, inside the route template I'm calling a component, and passing the controller's action to the component as a parameter. Just like documentation says in <a href="http://guides.emberjs.com/v2.2.0/components/triggering-changes-with-actions/" rel="nofollow">EmberJS 2.20 Triggering changes with actions</a><br>
  When I'm trying to call the <code>"parent"</code> action inside the component, the return is undefined, but if I throw on console, <code>"this"</code> element and inspect its attr, the function is there.<br>
  <strong>Controller js code:</strong></p>
  
  <pre><code>export default Ember.Controller.extend({
    firstName:'',
    lastName:'',
    actions: {
      addAlumn (){
        this.store.createRecord('alumn',{
          firstName : this.get('firstName'),
          lastName : this.get('lastName')
        });
      }
    }
  });
  </code></pre>
  
  <p><strong>Route hbs template:</strong></p>
  
  <pre><code>{{#validated-form submit=(action 'addAlumn') saveBtn=true }} ... {{/validated-form}}
  </code></pre>
  
  <p><strong>Validated-form hbs template</strong></p>
  
  <pre><code>{{yield}}
  {{#if saveBtn}}
  &lt;a href="#" class="btn primary save"{{action "validateAndSubmit"}}&gt;Add &lt;span class="icon-check"&gt;&lt;/span&gt;&lt;/a&gt;
  {{/if}}
  </code></pre>
  
  <p><strong>Validate-form js code</strong></p>
  
  <pre><code>export default Ember.Component.extend({
    actions : {
      validateAndSubmit(){
        console.log('validate');
        console.log(this);
        console.log(this.get('submit')());
      }
    }
  });
  </code></pre>
  
  <p>As I said, the results on console are:<br></p>
  
  <pre><code>&gt; validate
  &gt; Class {__ember1449505261281: "ember496", __ember_meta__: Meta, parentView: Class, HAS_BLOCK [id=__ember1449505261281400801945202]: true, _targetObject: Class…}
  &gt; undefined
  </code></pre>
  
  <p>Any clues on why this is not triggering the event? Maybe is because the guide example is working just with components and I'm using a controller?</p>
