Ajax pagination is causing issue

Hey Guys,
Please refer this screenshot.

Everything looks like its working but pagination is having an issue. Sometimes when I go back & fro, screen gets freeze like in screenshot.
Code looks just like examples snippets. Here is test url where I have setup demo.

Also I see some discrepancy in records nos when I go next & prev.
When I do next, it goes from 1,10 then 11,20 then 21,30 but when I click on prev when I am on 21,30 it comes back on 12,21.. Weird.. Also i think its not calling db as expected..

Please help me with it..
