title: AngularJS videogular not responsive
body: <p>I am using angularjs and I read that videoangular is automatically responsive  with vg-responsive='true'.
  But using this code:</p>
  
  <pre><code>&lt;videogular vg-responsive='true'&gt;
      &lt;video class='videoPlayer' controls preload='none' vg-responsive='true'&gt;
          &lt;source src='http://www.videogular.com/assets/videos/videogular.mp4'  type='video/mp4'&gt; 
      &lt;/video&gt;
  &lt;/videogular&gt;
  </code></pre>
  
  <p>the video on the browser is not responsive.
  Any idea?
  Thank you.</p>
