[feature]: need an event object in onChange handler

[kanweiwei]

Someone may want to mimic windows folder selection. For example, select multiple items hold down the CTRL key,or select a few items at the same time hold down the SHIFT key. To do that I need an event object in onChange handler so that i can get some attributes like crtlKey and shiftKey of e.nativeEvent.
