title: How do I bind event to sessionStorage?
body: <p>I can successfully bind an event for a change to localStorage (using jquery):</p>
  
  <pre><code>$(window).bind('storage', function(e)
  {
      alert('change');
  });
  
  localStorage.setItem('someItem', 'someValue');
  </code></pre>
  
  <p>If I use sessionStorage, the event will NOT fire:</p>
  
  <pre><code> $(window).bind('storage', function(e)
  {
      alert('change');
  });
  
  sessionStorage.setItem('someItem', 'someValue');
  </code></pre>
  
  <p>Why is this?</p>
