title: adding second model to route makes first undefined
body: <p>In my current Ember setup, I retrieve a store for the Index Route. This works fine.</p>
  
  <pre><code> App.IndexRoute = Ember.Route.extend({
  
      model: function(){      
            var store = this.store.find('index');        
            return store;
          }
  
    });
  </code></pre>
  
  <p>However, I wish to create a custom form object for the same route, and therefore following the advice of <a href="https://stackoverflow.com/questions/20521967/emberjs-how-to-load-multiple-models-on-the-same-route">this SO answer</a>tried to return two models for the Index Route like this, however, I now get the error</p>
  
  <pre><code>Error while processing route: index that is not defined ReferenceError: that is not defined
  </code></pre>
  
  <p>New Code</p>
  
  <pre><code>  App.IndexRoute = Ember.Route.extend({
  
      model: function(){      
  
            return Ember.RSVP.hash({
             store: this.store.find('index'),
             customform: App.CustomForm.create()
            });
         }
  
  
    });
  </code></pre>
  
  <p>How can I add a second model to this route? </p>
  
  <p>Update
  The index model had a date property that I was using to sort the items in the index model</p>
  
  <pre><code>App.IndexController = Ember.ArrayController.extend({
          sortProperties: ['date'],
          sortAscending: false,
  </code></pre>
  
  <p>I was originally displaying the index model with this in the html</p>
  
  <pre><code>    {{#each item in arrangedContent}}
   &lt;li&gt; {{some-component id=item.customid date=item.date data=item.junk}} &lt;/li&gt;
  
      {{/each}}
  </code></pre>
  
  <p>By adding the second model, whether or not i use the store to create a record, I get this error and the data from the store doesn't load in the html</p>
  
  <pre><code> Error while processing route: index undefined is not a function TypeError: undefined is not a function
  </code></pre>
  
  <p>Also, I don't actually need to persist the second model I'm trying to add, so I don't desire to make it a store. In the SO answer I linked to, second models were added that weren't persisted.</p>
