title: fb comments href not working whith angularjs
body: <p>I have installed below FB plugin on my page where I have specified data-href as below:</p>
  
  <pre><code>&lt;div class="fb-comments"  data-href="http://pingle.com/ngdemo" data-width="550px" data-numposts="5" data-colorscheme="light"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>But when I am trying to set a scope value to it to make URL speicific it is not taking it and while checking on firefox, value {{ post.id }} is not getting added to the URL in fb DIV.</p>
  
  <pre><code>    &lt;div class="fb-comments"  data-href="http://pingle.com/ngdemo?postId={{ post.id }}" data-width="550px" data-numposts="5" data-colorscheme="light"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>PS: when I print it on html, just above fb plugin, it displays nicely? is there a way to append scope value to data-href attribute of fb comment??</p>
