bug#24019: 25.1.50; Allow using a custom callback with xwidget

[Puneeth Chaganti]

Hello,

`xwidgets.el' seems to have some commented code that used to allow using
a different callback on each xwidget.  This functionality is useful to
have and this is a patch that uncomments this code.  I've tested the
code, and it seems to work, and I'm not really sure, why this was
commented in the first place.

Thanks!
