Use $._data to get event data as $(this).data('events') has been removed from jQuery 1.8+

jquery.prebind.js

$.fn.preBind = function(type, data, fn) {
  this.each(function() {
    var $this = $(this);

    $this.bind(type, data, fn);

    var currentBindings = $._data($this[0], 'events');
    if ($.isArray(currentBindings[type])) {
      currentBindings[type].unshift(currentBindings[type].pop());
    }
  });

  return this;
};
