title: Different Facebook comment box after each ajax call
body: <p>my problem is this:
  I've got a webpage that changes each time the user clicks the button. The title is updated, a graph. Seeing as the page now has different content, I would love to have a different commenting section. However, the url is exactly the same (because all of the content is ajax loaded) and so I'm wondering whether it is possible to have a new FB comment box be generated as well (it would need to be generated because there are hundreds of sets of content that the user can click through)?</p>
  
  <p>Thanks.</p>
