Facebook album pagination callback

Question

Hello,

I've tried to paginate an album that contains more than 25 images with Graph API. The returned JSON contains a "paging" property that leads me to two JSON strings, for example the "next page" is:

FB.ApiServer._callbacks.f24adb366({...

The problem is that I don't know what to do with this response. FB.ApiServer._callbacks.f24adb366 is undefined ( to be specific f24adb366() is undefined ) and I didn't find any help in the documentation that describes where to register these callback events.

I'm using the JavaScript SDK in an iFrame application.
