Is there any significant changes between onchange and addEventListener('change', ? Also in your new pull request #26 it still uses onchange. Should it also be changed to addEventListener?

I write a demo for their difference.

Only the lastest handler of onchange can be triggered.

See the link below for detail.

Yep. It's my miss.
