      Subscribe a callback function for each `Node` in the collection to execute
      in response to a DOM event.
  
      NOTE: Generally, the `on()` method should be avoided on `NodeLists`, in
      favor of using event delegation from a parent Node.  See the Event user
      guide for details.
  
      Most DOM events are associated with a preventable default behavior, such as
      link clicks navigating to a new page.  Callbacks are passed a
      `DOMEventFacade` object as their first argument (usually called `e`) that
      can be used to prevent this default behavior with `e.preventDefault()`. See
      the `DOMEventFacade` API for all available properties and methods on the
      object.
  
      By default, the `this` object will be the `NodeList` that the subscription
      came from, <em>not the `Node` that received the event</em>.  Use
      `e.currentTarget` to refer to the `Node`.
  
      Returning `false` from a callback is supported as an alternative to calling
      `e.preventDefault(); e.stopPropagation();`.  However, it is recommended to
      use the event methods.
  
      @example
  
          Y.all(".sku").on("keydown", function (e) {
              if (e.keyCode === 13) {
                  e.preventDefault();
  
                  // Use e.currentTarget to refer to the individual Node
                  var item = Y.MyApp.searchInventory( e.currentTarget.get('value') );

  Subscribe a callback function to execute in response to a DOM event or custom
  event.
  
  Most DOM events are associated with a preventable default behavior such as
  link clicks navigating to a new page.  Callbacks are passed a `DOMEventFacade`
  object as their first argument (usually called `e`) that can be used to
  prevent this default behavior with `e.preventDefault()`. See the
  `DOMEventFacade` API for all available properties and methods on the object.
  
  If the event name passed as the first parameter is not a whitelisted DOM event,
  it will be treated as a custom event subscriptions, allowing
  `node.fire('customEventName')` later in the code.  Refer to the Event user guide
  for the full DOM event whitelist.
  
  By default, the `this` object in the callback will refer to the subscribed
  `Node`.
  
  Returning `false` from a callback is supported as an alternative to calling
  `e.preventDefault(); e.stopPropagation();`.  However, it is recommended to use
  the event methods.
  
  @example
  
      Y.one("#my-form").on("submit", function (e) {
          e.preventDefault();
  
          // proceed with ajax form submission instead...
      });
  
  @method on
  @param {String} type The name of the event
  @param {Function} fn The callback to execute in response to the event
  @param {Object} [context] Override `this` object in callback
  @param {Any} [arg*] 0..n additional arguments to supply to the subscriber
  @return {EventHandle} A subscription handle capable of detaching that
                        subscription
