DT doesn't filter

hava

Hello. I am newbie with datatable and I have a problem with setting up. What I need is to implement filtering by keyword but when I type something nothing happen, though sorting works. Below my settings

DT settings
[code]
$(document).ready(function() {

oTable = $(".li_datatable").dataTable({
"sPaginationType": "full_numbers",
"bLengthChange": false,
"aaSorting": [[1]],
"bFilter": false,
"bAutoWidth": false,
"iDisplayLength": 10,
"aoColumnDefs" : [{"bSortable":false,"aTargets":[]}],
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "index.php?S=225bc46fff3ace69f1a87caa5195d6b3eecac377&D=cp&C=addons_modules&M=show_module_cp&module=linkedin_search&method=index",
"fnServerData": function (sSource, aoData, fnCallback) {
var extraData = $("#filterform").serializeArray();
for (var i = 0; i < extraData.length; i++) {
if (extraData[i].name == "perpage") {
$(".li_datatable").dataTable().fnSettings()._iDisplayLength = parseInt(extraData[i].value);
}
aoData.push(extraData[i]);
}
$.getJSON(sSource, aoData, fnCallback);
},
"oLanguage": {
"sZeroRecords": "no_entries_matching_that_criteria",
"sInfo": "Showing _START_ to _END_ of _TOTAL_ entries",
"sInfoEmpty": "Showing 0 to 0 of 0 entries",
"sInfoFiltered": "(filtered from _MAX_ total entries)",
"sProcessing": "Processing...",
"oPaginate": {
"sFirst": "",
"sPrevious": "",
"sNext": "",
"sLast": ""
}
},
"fnRowCallback": function(nRow,aData,iDisplayIndex) {

$(nRow).addClass("collapse");
return nRow;
}
});
oSettings = oTable.fnSettings();
oSettings.oClasses.sSortAsc = "headerSortUp";
oSettings.oClasses.sSortDesc = "headerSortDown";

});
// ]]>

> "bServerSide": true

So filtering is done entirely on the server-side. DataTables will send parameters to the server that will tell the server what the applied filter is, and it must then filter the data set as required and return the data to the client: http://datatables.net/usage/server-side
