Hello, Everyone and Happy new year!

I want to create new discourse plugin which sends posts and replies to GitHub issues.  
So, I fonund `:post_created` symbols on [discourse-official-slack-plugin](https://github.com/discourse/discourse-slack-official) and used it (like below example code).

```rb
DiscourseEvent.on(:post_created) do |post_id|
   post_id = post_id[:id]
end

```

But I failed to find event when updated posts and replies. I think `post_created` symbol defined by `PostAlterer` class at `app/services/post_alterer.rb`.

Therefore, I want to know

1. How to create events when update post or reply or where event defined.
2. If it is impossible, May I modify controller code directly for implementing my features?

Taehwan Kim.
