onChange not firing properly in React 15.2.0 + IE11 when paste text into textarea

[anggao]

Hello. On IE11/React 15.2.0 when copy/paste data from keyboard to a textarea, onChange not firing,
this works fine in Chrome and FF

I've included a test link:

(a log msg should happen when you copy/paste data into textarea)

Thanks!

And I found it seems keyboard copy/paste sometimes trigger the event sometimes not, and right click then select paste always failed to trigger the event

gonna say its the same issue as the rest without having looked into it? did it work in 14, and does it work using master? That it works sometimes suggests that itas due to the polyfill needing focus of the inputs...I would think the context menu version steals focus?

@anggao I have seen fiddle shared by you. Instead of onChange() use onInput(). I have tested it and its working fine for me.

@dhavalsoni2001 Thanks ! onInput() did work, but according to the React doc:
https://facebook.github.io/react/docs/forms.html

For <input> and <textarea>, onChange supersedes — and should generally be used instead of — the DOM's built-in oninput event handler.

@jquense I checked with 0.14.8 and it works:

@dhavalsoni2001 just found onInput() won't work in IE9 :(

And this issue seems only occurs in IE11

This works correctly on master.

This issue is still present in version 15.3.0 when pasting with mouse: https://jsfiddle.net/pwy1xedh/
It does work when pasting with keyboard. Only IE 11 seems affected, Chrome and Edge work fine

My team also verified this on 15.3.0 in IE11, but only when pasting with the mouse. Pasting with the keyboard works fine. We are using onInput instead now, as others have mentioned. Not sure if this is the right thing to do, but it's the only option until this gets fixed.
