Child rows problem

supriya

Hello,I am using Datatables 1.10. I am passing parameters eg. from date,to date to via ajax and on button click search results are displayed.
I have also used example at http://datatables.net/examples/api/row_details.html to display information.
My problem is when page is loaded for first time,rows are expanded successfully. but when I change parameter and click on search,result is displayed but click event is not working to show row details.When i again click on search button with same parameters ,event works.Please let me know why this is happening.
My Code is as follows:

$(document).ready(function() {

            $("#btnSubmit").click(function(){
                                   if ( $.fn.DataTable.isDataTable( '#records' ) ) {
                                        var temp = $('#records').DataTable();
                    temp.destroy();
                }

                table = $('#records').DataTable( {
