I used jquery data table for sorting. It works fine under normal condition. If i changed the value in run time, the sorting is not working.

This is my table data 

        <table width="94%" cellpadding="2" cellspacing="1" class="tablehead" id="pls-batting">
    <thead>     
    <tr class="tab_head" align="right" id="pls-play" >
    <th width="44" align="center" ># No </th>
    </tr>
    </thead>
    <tbody>
    <tr  id="116706">
    <td align="left" id='1' >test</td>
    </tr>
    <tr id="116707">
    <td align="left" id='2'>bbb</td>
    </tr>
    <tr id="116708">
    <td align="left" id='3' >xxx</td>
    </tr>
    </tbody>
    </table>

Jquery method used for sorting is : 

 $(document).ready(function() {

   $('#pls-batting').dataTable( {

            } );
  } );

By clicking the ‘# No’ head the corresponding column displayed in asc and desc order respectively. These TD values will be changed onload by using 

        document.getElementById(3).innerHTML = 'something';

So as a result the 3rd column value is ‘something’. So sorting will be done by this values. But it is not working.

It takes the old values. Please help me. Thanks

    In DataTables, you should not update content of HTML cell. DT uses internal JavaScript array structure for searching/sorting and this cell is only a display value.

    To update some cell you will need to use DT fnUpdate function see http://datatables.net/api#fnUpdate. Example of updating cell in the table is:

    var oTable = $(‘#example’).dataTable();
    oTable.fnUpdate( ‘New content’, 10, 3 );

    Note that cells are referenced by row/cell positions. If you don’t know row/cell position then you can use http://datatables.net/api#fnGetPosition function to find position of TR with id 3 and use this info to update cell data using the fnGetData function (you can find example on the http://datatables.net/api#fnGetPosition)
