title: Knockout.js - enable binding for scope
body: <p>I'm looking for the best way enable or disable scope (all children elements of block) by knockout.js. Ideally, it should look like this:</p>
  
  <pre><code>&lt;div data-bind="enable:isEnabled()"&gt;
      &lt;input type="text" data-bind="value: val1" /&gt;&lt;br&gt;
      &lt;input type="text" data-bind="value: val2" /&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>This code is not working now (<a href="http://jsfiddle.net/NquQK/" rel="nofollow">http://jsfiddle.net/NquQK/</a>). How can i implement that? Maybe ready-made bindings or plugins exist for this task already?</p>
