html bootstrap Datatable is not working in aspx page.

I have use html jquery bootstrap datatable for sorting and serching data in my project.

I have retrive all the html datatable code from c# code using ajax and trying to add in div.

but datatable is not working functionally. there is not serch textbox and pagignation showing in view.

but when i add this datatable directly in aspx page insted of retrive datatable code from c# it's working fine.

I think when i retrive datatable html code from c# code browser not consider as html code.

I have use below javascript code for add datatable html code in div.

document.getElementById("tbl").innerHTML = obj;

Kindly help.
