jQuery Grid Plugin - jqGrid

Hi,

I am trying to use inline editing (with clientArray setting) in jqGrid 3.4.4 (with patch as well), following is my code. However, when I try to save a row by entering "Enter" key, it doesn't call afterSave function and displays "Loading..." above grid's title bar and is stuck there.  I also see an error printed "referenceError: Can't find variable: res" on the console. I am using HTML/Javascript inside Adobe Air.

Is my code correct or am I using editRow and saveRow correctly?

Any help is greatly appreciated.

Thanks

Babu

           function onEdit(rowid) {
                alert("Edit Called");;
            }

            function onSuccess(res) {
                alert("Success Called");;
            }

            function afterSave(rowid, responseText) {
                alert("After save Called");;
            }

            function onError(res, stat) {
                alert("Error Called");;
            }           

            function createCustomersGrid() {
                jQuery("#customers").jqGrid({
                    datatype: 'clientSide',
                    colNames:['Name','Address'],
                    colModel :[
                        {name:'name',index:'name', width:300, sorttype:'text', editable:true, edittype:"text", editoptions:{size:30}},
                        {name:'address',index:'address', width:300, sorttype:'text', editable:true, edittype:"text", editoptions:{size:50}}],
                    pager: jQuery('#customers_pager'),
                    rowNum:10,
                    ondblClickRow: function(id){
                        if(id && id!==customersLastSel){
                            jQuery('#customers').restoreRow(customersLastSel);
                            customersLastSel=id;
                        }
                        air.trace("The row selected is [" + id + "]");
                        jQuery('#customers').editRow(id, true, onEdit, null, "clientArray", {}, afterSave, onError);
                    },
                    viewrecords: true,
                    imgpath: 'lib/jquery/themes/basic/images',
                    caption: 'Customers'
                });

                if (!customersGridInitialized) {
                    var data = getLatestCustomers();
                    for (i = 0; i < data.length; i++)
                    {
                        var row = data[i];
                        $("#customers").addRowData(i+1, row);
                    }
                    customersGridInitialized = true;
                }           
            }
