Update value in fnRender column

ramirez

Sorry for my bad english, but exist 'clear' way to update data (fnUpdate) in fnRender column ?

[code]
$("#grid tbody tr").live("dblclick", function () {
var rowID = oTable.fnGetPosition(this);
var aData = oTable.fnGetData(this);
var iId = eval(aData[0]);
var rand = Math.random(9999);
$.get("__control/manage_maillist.asp", {"id": iId, "rand": rand},
function(data){
/* not complete */
oTable.fnUpdate("new image", rowID, 3 );
});
});

var oTable;
oTable = $('#grid').dataTable( {
"fnDrawCallback": function ( oSettings) {
if ( oSettings.bSorted || oSettings.bFiltered )
{
for ( var i=0, iLen=oSettings.aiDisplay.length ; i
