Problem is that you really can't rely on requested page index on purpose you try to implement. Reason for the behavior you're facing is that once you flip through pages forward, only 'next page' is requested, in which case index seems to be what you're expecting. But changing pages backwards works the exact opposite, only 'previous page' is requested, and there's a gap within index between these separate operations.
There's a method CurlView.getCurrentIndex() though which is constantly set to index of the page being shown on right side. It should give you means for having actual page numbers shown.
