jQuery Grid Plugin - jqGrid

Hi Forum members,

My delete pop-up does not go away after successful or unsuccessful delete in IE. The same code works well in mozilla.

i don't find any problem in firebug to debug this.

code snippet added below

   jQuery("#grid").jqGrid( 'delGridRow', row,
                         {  url:'${url}',
                             caption: "Delete Printer", msg: "Delete selected printer(s)?", bSubmit: "Delete", bCancel: "Cancel",closeOnEscape:true,reloadAfterSubmit:true, closeOnEscape:true,resize:false,
                            onclickSubmit : function(eparams) {
                                        var rowData = jQuery("#grid").getRowData(row);
                                        var retarr = {'id':rowData['id']};
                                        return retarr;
                                    },
                       afterSubmit : function(data,postdata) {
                                         if (data.responseText=="ok"){
                                            // Do something
                                         }
                                         else{
                                             // Do something
                                         }
                                         return(true,"ok")
                                        }

Can someone help on this behaviour and do i have to make any changes for for it to run on IE
