title: Ember data commit()
body: <p>This has been asked multiple times, however nothing has worked for me.</p>
  
  <pre><code>App.CatalogAddRoute = Ember.Route.extend({
      // other stuff ...
      actions: {
          save: function() {
              this.get('store').createRecord('category', {
                  category_id: 4,
                  category_name_fr_sh: "wat"
                  //... other properties
              });
              this.get('store').commit();
              this.get('target.router').transitionTo('catalog.index');
          }
      }
  });
  </code></pre>
  
  <p>I can see in my Ember toolbar that my createRecord did work. One more Category has been add to my controller. But the commit() always throws me the same error:</p>
  
  <pre><code>Object [object Object] has no method 'commit' 
  </code></pre>
  
  <p>Anyone has a hint here at what could be wrong ? </p>
