Knockout bindings for jQuery UI widgets
Knockout is a JavaScript library that makes it easier to create rich, desktop-like user interfaces with JavaScript and HTML, using observers to make your UI automatically stay in sync with an underlying data model. It works particularly well with the MVVM pattern, offering declarative bindings somewhat like Silverlight but without the browser plugin.

This project provides custom bindings for jQuery UI widgets. One way binding could be implemented fearly easy. However two-way binding makes some complexity and this project should solve them.
