Deleting all table row by checkbox

I am using checkbox for deleting rows separately and also using one checkbox(Select all) for checking all the checkboxes and deleting all rows.All the individual checkboxes are working correctly.But if i check the select all checkbox it only check the first page checkboxes and other page checkboxes are not checked.So help me how to check all the checkboxes for all the pages in pagination.

{

    <script type="text/javascript">

         $(document).ready(function () {
        $('#testtable').dataTable();
    });

   </script>



<script>  








    //SelectAll checkBox
    /****************************/
    $(document).ready(function(){ 

    $('#checkall').click(function(){
        if(this.checked)
        {
            $('.delete_checkbox').each(function(){
                this.checked=true;
                $(this).closest('tr').addClass('removeRow');
            });
        }
        else
        {
            $('.delete_checkbox').each(function(){
                this.checked=false;
                $(this).closest('tr').removeClass('removeRow');
            });
        }
    });
    /********************************/


    //Select indivisual checkBox
    /*******************************/
    $('.delete_checkbox').click(function(){

        if($(this).is(':checked'))
        {
            $(this).closest('tr').addClass('removeRow');
        }
        else
        {
            $(this).closest('tr').removeClass('removeRow');
        }
    });
    /*******************************/











});


</script>
