title: jQuery.off() is not removing binding
body: <p>For some reason jQuery.off('click') doesn't seem to be working here. When the 'Yes' button is clicked in the model another model just pops up. What am I doing wrong?</p>
  
  <p>code:</p>
  
  <pre><code>$(function(){
  
    //If there are warnings on the page bind alert
    if ($('.renewal-warning').length &gt; 0){
  
      (function (){
  
        $('#signRentalContainer').on('click', '.renewal-warning', function(e){
  
          var buttonHandle = this;
  
          //Prevent submission
          e.preventDefault();
  
          //Show warning model
          $.modal({
            content: $('#renewalWarning').html(),
            title: "Order Renewal Warning",
            buttons: {
              'Yes': function(win) { $(buttonHandle).off('click').click(); },
              'No': function(win) { win.closeModal(); }
            },
            maxWidth: 250,
            closeButton: false
          });
        });
      })();
    }
  });
  </code></pre>
