title: How do I render multiple outlets in one template file using ember 2.3
body: <p>I'm trying to render multiple .hbs snippets into their respective outlets. However, the following renderTemplate does not work:</p>
  
  <pre><code>renderTemplate: function() {
       // default behavior, renders the home template
       this.render(); 
        this.render('hero', {    // render the `hero` template
         outlet: 'hero'  // using the outlet named `hero`
       });
     }, 
  </code></pre>
  
  <p>The template file in question looks like this:</p>
  
  <pre><code>{{outlet 'hero'}}
  {{outlet}}
  </code></pre>
  
  <p>This actually renders the default template (this is the index route) twice: once in the hero outlet, and once in the regular outlet. </p>
  
  <p>This seemed to work in ember1.7, even if the hero outlet was included in the application.hbs template. Not quite so with ember2.3. </p>
  
  <p>How would I make this work?</p>
