title: How to get an observableArray's length?
body: <p>I am attempting to create an array of contract line items (CLINs) that will be displayed as individual <code>div</code> elements below a header of general contract information.</p>
  
  <p>I am able to get the normal observables to work, but it appears that the passing of the array via the constructor for the view model is not creating any part of the clins observable array. </p>
  
  <p>I have a <a href="http://jsfiddle.net/TuRrs/3/">jsFiddle that illustrates my problem</a>.  What is strange to me is that the <code>data-bind="text: clins.length()</code> on the HTML span tag does not even return zero, but instead renders nothing.</p>
  
  <p>Is there anyway to enable debugging within a jsFiddle or should I see a warning/error?</p>
