DataTables

Hi, I have problem with this code

         var detailTable;
        var openDialog = function(id) {

            detailTable.fnReloadAjax( 'service/detail/'+ id );
            console.log(detailTable);
            $("#detailsBlock").modal({
                overlayClose:true,
                opacity:70,
                overlayCss:{backgroundColor:"#eee"}
            });
        }

Problem appear after second call(first one after page load works perfect) openDialog. DataTables just "Processing" my server tell in log that everything fine and data has been send. I just use fnReloadAjax from this page http://datatables.net/plug-ins/api. And there is no mention about that problem.
table init code in ready() section

detailTable = $('#details').dataTable({
                /*"sAjaxSource":"service/details",*/
                "bProcessing":true,
                "bServerSide": true,
                "bDestroy": true,
              /*  "bDeferRender":true,*/
                "aoColumns":[
                    { "mDataProp":"lineNumber" },
                    { "mDataProp":"supplierItemCode" },
                    { "mDataProp":"itemDescription" },
                    { "mDataProp":"invoiceQuantity" },
                    { "mDataProp":"invoiceUnitNetPrice" }
                ], "fnServerData":connectPost

            }); 

Any ideas? :)
