title: How to include scope parameters in Fb login button
body: <p>I have been trying to add scope parameters using the below code.</p>
  
  <p>When i add scope the button is not rendered. If i remove the scope then the button is rendered.</p>
  
  <pre><code>&lt;div class="fb-login-button" data-max-rows="1" data-size="medium" data-show-faces="false" data-auto-logout-link="false" &gt;&lt;/div&gt;
  
  
  &lt;div class="fb-login-button" data-max-rows="1" data-size="medium" data-show-faces="false" data-auto-logout-link="false" scope="email,username" &gt;&lt;/div&gt;
  </code></pre>
  
  <p>fb login also makes use of javascript in such fashion.</p>
  
  <p>Is there a way i can add the scope directly to the button without calling the scope in js.</p>
  
  <pre><code> FB.login(function(response) {
                   testAPI();
   }, {scope: 'email,user_likes,username,publish_stream'});
  </code></pre>
