title: JQuery Unbind and then bind
body: <p>I've found lots of examples on this topic.. however, I do not fully understand.  Does my logic seem correct?  I have a div as button (class of .myClass) and I don't want it clickable unless myCount >= 1.</p>
  
  <pre><code>// I want to unbind if myCount == 0
  if ( myCount == 0) {
   $('.myClass').unbind().css("opacity","0.5");
  } else {
   // **would this rebind?**
   $('.myClass').click(callMyFunction);
  }
  </code></pre>
