  <p>How to update ko.observable text on the click event?
  I could do this using "afterkeydown" or "keypress" but not in case click event.<a href="http://knockoutjs.com/documentation/value-binding.html" rel="nofollow">http://knockoutjs.com/documentation/value-binding.html</a></p>
  
  <pre><code>&lt;span data-bind="text: Count"&gt;&lt;/span&gt;
  &lt;button data-bind="click: update"&gt;Update&lt;/button&gt;
  
   function MyViewModel() {
       var self = this;
  
       self.Count = ko.observable("0");
  
       self.update = function() {
           self.Count = ko.observable("1");
       }
   }
  </code></pre>
