fnFilter doesn't work in 1.10 with serverside processing

Hi,

I have trying fnFilter in DataTables1.10 but it got an error in firebugs "TypeError: oTable.fnFilter is not a function", here is my code :

    $(document).ready(function() {
    var oTable = $('#example').DataTable( {
        "fnRowCallback": function( nRow, aData, iDisplayIndex ) {               
            $(nRow).attr({"onmouseover":"this.className='mouseover'", "onmouseout":"SetBackground(this,this.rowIndex);", "onclick" : "showEquip(" + aData[9] + ",\"<?php echo $sid;?>\");return false;"});
            return nRow;
        },          
        "oLanguage": {
            "sSearch": "Search all columns:",               
            "sLengthMenu": 'Display <select style="margin-right:5px;"><option value="10">10</option><option value="25">25</option><option value="50">50</option><option value="100">100</option><option value="250">250</option><option value="-1">All</option></select>records&hellip;'                
        },
        "bJQueryUI": true,
        "sPaginationType": "full_numbers",          
        "sDom": 'T<"clear"><"H"lr>t<"F"ip>',
        "oTableTools": {
            "sSwfPath": "media/swf/copy_csv_xls_pdf.swf",
            "aButtons": [
            {
                "sExtends": "copy",
                "mColumns": "visible"
            },
            {
                "sExtends": "csv",
                "mColumns": "visible"
            },
            {
                "sExtends": "xls",
                "mColumns": "visible"
            },
            {
                "sExtends": "pdf",
                "sPdfOrientation": "landscape",                 
                "mColumns": "visible"
            },
            "print"
            ]
        },          
        "bSortClasses": false,
        "iDisplayLength": 25,           
        "processing": true,
        "serverSide": true,
        "order": [[2, 'asc']],
        "ajax": "modul/mod_equip/server_processing.php"
    });

    new $.fn.dataTable.FixedHeader( oTable );

    $("#catId").change(function(){
        oTable.fnFilter("^"+$(this).val()+"$", 10, true);
    });

Can anybody help me with that error?

Thanks
