title: Knockout JS -Radio click event not updating the DOM
body: <p>DOM:</p>
  
  <pre><code>self.setVisible=function(question,event){
      alert(event.target.value);
      question.answer(event.target.value)
      alert(event.target.value);
  }
  </code></pre>
  
  <p>The click event inside array of knockout js radio button is not updating the DOM
  Explanation of Problem:</p>
  
  <pre><code>&lt;input type="radio" data-bind='click: setVisible' value="Yes"  /&gt; Yes 
  &lt;input type="radio" data-bind='click: setVisible' value="No"/&gt; No
  </code></pre>
  
  <p>There are two radio button Yes and No,generated dynamically in an array.If I add a click event the selected checkbox is not updating.</p>
  
  <p>Now,When I click yes first it is checked but from the next time if i click "No" again Yes is only getting checked.I am wondering whats wrong.</p>
  
  <p>Note:If I remove the click event its working perfectly.Please find the DOM in the comment I have added.   </p>
