Custom events doesn't bubble

[enzy]

And there is no way to tell them to. Or am I wrong?

I have:

<form>
  ...
  <input>
  ...

Input fires custom event on itself. Form doesn't catch it.

Also note that Event.initEvent() is deprecated, see https://developer.mozilla.org/en-US/docs/Web/API/Event/initEvent
