title: Request Dialog not sending requests to friends
body: <p>I'm trying to implement a simple request option in my app using the following code</p>
  
  <pre><code>FB.ui({
      method: 'apprequests',
      title: 'My app title',
      message: 'Hi there, join my app'
  }, function(response) {
      console.log(response)
  });
  </code></pre>
  
  <p>This shows up the dialog, allows me to select my friends, when I send it I get a proper response back. (So an array with all my friends)</p>
  
  <p>But none of my friends actually see this request, I had another account open and kept inviting it, but nothing shows up on that account.</p>
  
  <p>Am I still missing something here?</p>
  
  <p>So in short, the dialog shows up, I can invite my friends, but my friends don't get any notification.</p>
