title: Knockout js hide button if value is greater than
body: <p>I am defining a variable after the page load (storing numerical json data)</p>
  
  <p>I can successfully put this variable in:</p>
  
  <pre><code>&lt;span data-bind="text: extQty"&gt;&lt;/span&gt;
  </code></pre>
  
  <p>And when the variable changes it updates the span with the appropriate variable (That works fine).</p>
  
  <p>But it doesn't update my variable within my enable:</p>
  
  <pre><code>&lt;p class="pull-right"&gt;&lt;a class="btn btn-primary" data-bind="click: $root.add, enable: pagedList().length &lt; extQty" href="#" title="edit"&gt;&lt;i class="icon-plus"&gt;&lt;/i&gt; Add Extension&lt;/a&gt;&lt;/p&gt;
  </code></pre>
  
  <p>I need to have the enable effectively disable based on the value that is presented to "extQty". Right now I'm sending 5 to the extQty, and it seems the variable is only updating inside the "text" data-bind rather than the "enable" data-bind.</p>
