title: FBInstant.shareAsync() function doesn't work without any errors in facebook instant game Share button
body: <p>I created a facebook instant game and in the end there's a share button, how to make that share button shares the result or a photo in a link to play the game on the player's profile.
  Here's my code of the shareAsync() function, which produces no javaScript errors but yet doesn't work.</p>
  
  <pre><code>$(document).on("click", ".share-result", function(){
     FBInstant.shareAsync({
         intent: 'INVITE',
         image: img,
         text: 'Play this Awesome game',
         data: {myReplayData: '...'},
     }).then(function() {
         location.reload();
        });
  });
  </code></pre>
