Title: Event: Add reference to data module ...

Since we are using _data() quite a lot in event.js, it deserves a ref.
(It is actually broken if we reference unpacked jquery.js using AMD loader, an exception will be thrown at line:314 of event.js)

ps: on master branch, the "event.js" already correctly referenced prvtData which is the equivalent of _data().
