Using jquery-ui datepicker with Dotvvm 4.3 TextBox control

Are there any examples of using jquery-ui datepicker on a TextBox with Dotvvm 4.3? I can get the calendar to appear and I can select a date. The correct date is displayed in the text box, but when the form is submitted nothing is saved. I can type a date into the text box and submit and it is saved. I think my problem is Knockout JS value-binding related.

I guess that jquery ui datepicker doesn’t trigger the change event on the input when you select a value from the calendar. Can you post a snippet of a code so I can see how the syntax looks like?
