title: Using knockoutJS, how to create a multi-selectable list
body: <p>I am trying to have the functionality of the <a href="http://jqueryui.com/demos/selectable" rel="nofollow noreferrer">jQuery selectable list</a> when using KnockoutJS, but can't get it to work.</p>
  <p>Using Custom Bindings I was successful in transforming <code>ul</code> element in a selectable one and creating events handlers for the selected and unselected events.  But what do I pass to my ViewModel functions which maintain the selected elements?</p>
  <p>Here is my code so far: <a href="http://jsfiddle.net/QCmJt/" rel="nofollow noreferrer">http://jsfiddle.net/QCmJt/</a></p>
  <p>I am new to all this, so maybe I am approaching this the wrong way...</p>
