title: Refreshing an Ember.View when the controller route changes
body: <p>I have a subclass of Ember.TextArea that displays some text from my model.</p>
  
  <p>The View is rendered when the user goes to /:model_id</p>
  
  <p>If the user is viewing /2, and then goes to /3, none of my lifecycle events are being called in the view.  didInsertElement isn't touched.  Only the value of the text area is changed with the new model.</p>
  
  <p>What I really want to do is focus the text area every time the user goes to a /:model_id.</p>
  
  <p>Any ideas?</p>
