Jquery serialscroll problem


I am using serialscroll plugin for jquery by Ariel Flesler. I am trying to make the vertical scroller to have continues loop without reverting back to first item (which is default functionality).

To have continues loop of items i tried to append the items which is working fine and able to achieve when i click on “NEXT”. However problem seems to be with “Previous” link where i am trying to prepend the items at the top, it is pending the items however changing the visible items.

I understand that prepending the items is causing the index of items to change which is normal. So what i am looking for it to keep showing the visible items even when prepending.

Please see this URL where i have put the problem i am facing : Untitled Document

Please suggest.
