    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

`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
