Rough transitionEnd binding for Knockout

ko.bindingHandlers.transitionEnd.js

/*
 * Sample usage:
 *    <div data-bind="transitionEnd: modelMethod"></div>
 *
 * Issues:
 * - Webkit-only event name
 * - Fires multiple times when multiple properties are transitioned
 */
ko.bindingHandlers.transitionEnd = {
  init: function (element, valueAccessor) {
    ko.utils.registerEventHandler(element, "webkitTransitionEnd", function (event) {
      var callback = valueAccessor();
      callback(ko.dataFor(element), event);
    });
  }
