title: ng-src attribute in an iframe doesn't accept expressions ? using Angular.js
body: <p>I am trying to display the youtube video of a specific ID that i can take out of my array. I use an expression to fill in this ID at the right place in my ng-src attribute , but it doesn't work. I used the same expression above the i-frame to see if the expression is working , and it did. </p>
  
  <pre><code>&lt;iframe allowfullscreen="" 
          frameborder="0" 
          height="315" 
          ng-src="http://www.youtube.com/embed/{{selectedSong.youtube_ids.default}}?rel=0?rel=0&amp;amp;hd=1" 
          width="560"&gt;
  &lt;/iframe&gt; 
  </code></pre>
  
  <p>As you see i used the <code>{{selectedSong.youtube_ids.default}}</code> expression for my id but when I inspect my html when running it is displaying the expression instead of the result (so I'm sure it isn't working).</p>
