Window.opener.parent changes

Hello,
We have a data table shown on a jsp page.Clicking on row we show details of that record on an popup window. Now on popup we have a next and previous button where basically on a popup window i want to read the data tables rows .

I am able to fetch the next and previous using the data table plugin but its working only once.
After that the parent window url is changing .

Can someone please help me with this ?

Thanks a lot in advance !
