Slow to hide/unhide columns/rows

i am coping data in kendo spreadsheet cell but it is taking too much time as because evry time firing change event. I have used batch method but still not getting any improvement.

function OnPeriodChange(e) {
  
    var period = $("#ddlPeriodEnding").val();

    var cellVal = $("#ddlcells").val();
    var cellText = $("#ddlcells").data("kendoDropDownList").text();

    var spreadsheet = $("#spreadsheet").data("kendoSpreadsheet");
    var sheet = spreadsheet.activeSheet();
    var range = sheet.selection();
    var values = range.values();

   

    sheet.batch(function () {
        FillBalanceSheet(period, cellVal, cellText, sheet);
        //sheet.range(cellVal + "1" + ":" + cellText + "200").select();
    }, { layout: false });

    //e.preventDefault();
   
}

even I am also using change metod in batch

sheet.batch(function () {

        sheet.bind("change", function (e) {

            var range = sheet.selection();
            var values = range.values();

            if (range._ref.bottomRight.row == 0) {
                if (values.length == 1 && values[0][0] != null) {
                    $("#ddlPeriodEnding").data("kendoDropDownList").value(values[0][1]);
                    $("#ddlPeriodEnding").data("kendoDropDownList").text(values[0][0]);
                }

                var selCell = cols[range._ref.bottomRight.col];

                var colPos = getKey(selCell, colText);

                if (colPos != undefined) {
                    $("#ddlcells").data("kendoDropDownList").text(colPos);
                    //var x = $('#ddlcells').data("kendoDropDownList").dataItem(colPos);
                   // $("#ddlcells").data("kendoDropDownList").value(x.Value);

                }
                else {
                    var selNextCell = cols[range._ref.bottomRight.col + 1];
                    var colPosnext = getKey(selNextCell, colText);
                    if (colPosnext != undefined)
                    {
                        $("#ddlcells").data("kendoDropDownList").text(colPosnext);
                        //var x = $('#ddlcells').data("kendoDropDownList").dataItem(colPosnext);
                       // $("#ddlcells").data("kendoDropDownList").value(x.Value);
                    }
                   

                }


            }

        });

    }, { layout: false });

please suggest.
