“Paging within Modal”

Great plugin!

I have a list of items from a custom post type (portfolio_items).
Each of them has modal=true.

When I click on ony of the items the modal shows up just fine.
It also displays arrows for the next an previous post. But when
I click on the arrow, there is a a reload and the post shows up
like a normal call rather than updating the current modal or
closing the current and opening a new modal.

Please advise.
