Next and previous pagination buttons not working after storing and re appending data table html

akhil

I an displaying a list of devices in datatable. My data table is displayed inside a div of id="content". When clicking on each row i stores html contents of content div into javascript variable as
var html=$('#content').html();

then loading details.html into content div. when i click on a back button html is again inserted into content div. then calls fnReloadAjax(null,null,true); After that data table is working properly except prev, next ,last and first buttons. clicking on page numbers works. Please give me a solution. thanks in advance
