jQuery UI datepicker onSelect NOT working-CodePudding

I have From Date and To Date jQuery datepicker controls and if I change From Date, then To Date should automatically be 180 days from From Date

Below code is not firing the onSelect event even if this looks so simple...

$("#txtFrom").datepicker({
        minDate: 0,
        onSelect: function (dateStr) {
            var newDate = $(this).datepicker('getDate');
            if (newDate) {
                newDate.setDate(newDate.getDate()   180);
            }
            $('#txtTo').datepicker('setDate', newDate).datepicker('option', 'minDate', newDate);
        }
    });

Also, I require onChange event to be fired...

Any help would be greatly appreciated.
