title: How to know when a Backbone model.fetch() completes?
body: <p>I bind on the change event of my backbone models like this.</p>
  
  <pre><code>this.model.on( "change", this.render, this );
  </code></pre>
  
  <p>Sometimes I want to fetch the latest version of the model and forcibly render the view.  So I do this</p>
  
  <pre><code>this.model.fetch();
  </code></pre>
  
  <p>Unfortunately model.fetch() only fires the change event if the new data is different from what was previously stored in the model.</p>
  
  <p>How can I always trigger a this.render callback when fetch completes, whether it triggers a change event or not?</p>
  
  <p>Thanks (in advance) for your help</p>
