title: jQuery off() not working with an events-map
body: <p>I'm trying to use the events-map property in <code>jQuery.off()</code> to disable events, but it doesn't seem to disable the events.</p>
  
  <p>According to the jQuery docs <code>off()</code> should use the keys of the events-map and ignore the values.</p>
  
  <p>Here's an example:
  <a href="http://jsfiddle.net/tNBMM/" rel="nofollow">http://jsfiddle.net/tNBMM/</a></p>
  
  <p>Checking the checkbox should do a simple hover effect. Unchecking it calls the <code>off()</code> function, which (as I see it) should disable the events, but doesn't.</p>
  
  <p>What am I doing wrong here?</p>
