Datepicker Not Updating Model Value

[bernesto]

I "may" be missing something. I can change the datepicker values when I update the model manually (via console), but when the datepicker itself is changed, it does not update the model. I can work around this by setting the model value in the onSelect event. But, it seems that this should be unnecessary.

<script>
var model= function(data){
        var self = this;
        self.checkInDate = ko.observable(data.CheckInDate);
        self.checkOutDate = ko.observable(data.CheckOutDate);
}
</script>

<div id="checkIn" data-bind="datepicker: {
    value: checkInDate,
    minDate: '+2w',
    showOtherMonths: true,
    selectOtherMonths: true,
    changeYear: true,
    changeMonth: true,
    onSelect: function (selectedDate) {
        $('#checkOut').datepicker('option', 'minDate', selectedDate);
    }
}"></div>
<div id="checkOut" data-bind="datepicker: {
    value: checkOutDate,
    minDate: '+15d',
    showOtherMonths: true,
    selectOtherMonths: true,
    maxDate: '+12M',
    changeMonth: true,
    onSelect: function (selectedDate) {
        $('#checkIn').datepicker('option', 'maxDate', selectedDate);
    }
}">

Using:
Knockout 3.2.0
Knockout-jqueryui 2.2.2
Jquery 1.8.2
Jquery 1.11.1
Chrome Latest

Let me know if there are any incompatibilities, missing elements, or if this is a bug.

Thanks,
