title: Knockoutjs bind mouseover or Jquery
body: <p>I have this code in jquery. How would I write this in knockout with binding.
  Or is it better to have it in jquery. Is there a smart way to know when to write it in binding or in jquery? This is more viewstuff so maybe it should be in Jquery ?</p>
  
  <pre><code>$("body").on("mouseover mouseout", '.hoverItem', function () {
      $(this).toggleClass('k-state-selected');
  });
  </code></pre>
