title: Can I call function outside viewmodel on knockout?
body: <p>Let's say I want to call my plain javascript function on one of my data-binding. Is it possible to do so?
  I have tried:-  </p>
  
  <pre><code>&lt;span data-bind = "click : outsideFn() "&gt;hi&lt;/span&gt;
  
  &lt;span data-bind=" click : function() { outsideFn() } "&gt;hi&lt;/span?
  </code></pre>
  
  <p>Obviously, my attempt was unsuccessful.</p>

  <p>Edit:- Adding jsfiddle on the tag as this seems to be an issue with jsfiddle.</p>
