title: Changing meta facebook og with jQuery
body: <p>I have a problem (obviously),
  I've done a form that sends data in AJAX.
  I get the return value from my request when it success and I append it in the og tag content.
  for example</p>
  
  <pre><code>$('meta[property="title"]').attr('content', data.title);
  </code></pre>
  
  <p>after what when I check Elements in my chrome console, these changes are done.
  But if i click on the Facebook share button, it doesn't care about my changes...
  At the end , all what I want to change is the og tag title, description and image.</p>
  
  <p>Any solutions ?
  Thanks everyone.</p>
