 > ##### Callback only works with camel case string after v0.6.5
 > Lowercase string has been used for basic event name(ex: `oninit`, `onenter`, `onfocus`, `onblur`, `onkeyup`, `onkeydown`, `onpaste`). In contrast, callbacks name for advanced feature has been used with camel case string. This is inconsistent and confusing to use. So we rename all lowercase callback to camel case string.
