Change option dynamically in JQuery UI DatePicker fails

I want to make date range selection using jquery-ui datepicker. First change at #dteStart succeed to set minDate at #dteEnd. But #dteEnd failed to refresh its options on next change, if i alert DateOptions.minDate its value changed according to dateMin.

Maybe i miss something here...

$(document).ready(function () 
{
    $("#dteStart").datepicker()
    .change(function () 
    {
        dateStart = $(this).datepicker('getDate');
        dateMin = new Date(dateStart.getTime());
        dateMin.setDate(dateMin.getDate() + 1);

        var DateOptions = {
            dateformat: "mm/dd/yyyy",
            minDate: dateMin
        }
        $("#dteEnd").datepicker(DateOptions);
    });
});

TIA,
