title: Dynamic NG-Controller Name
body: <p>I want to dynamically specify a controller based on a config that we load. Something like this:</p>
  
  <pre><code>&lt;div ng-controller="{{config.controllerNameString}}&gt;
      ...
  &lt;/div&gt;
  </code></pre>
  
  <p>How do I do this in angular? I thought this would be very easy, but I can seem to find a way of doing this.</p>
