Next is not working with IE8

Hi,

I am trying to make data tables work with IE7 and IE8. The page works correctly in IE9 but in IE8, I get the "last" button working correctly, "first" button showing previous records, "previous" button showing next records and "next" button doing nothing.

My page code is here http://jsfiddle.net/hunkyhari/xC5c6/1/.

Please let me know if there is any solution to this issue.
