Actually this is what is doing the code linked by Gunu, nothing more.

Look at this:

Is there a way to custom that code in order to make bump the whole discussion when somebody is commenting under the blog article?

This is working well on the activity stream, but it’s not working if the comment is published in the blog post.
The activity in the stream is updated with the new comment, but it’s not bumping up.

Is there a way to make it working with it too?
