Remove command Callbacks (TEXT_RECOGNIZED).

[kaiknox]

So I am trying to build an assistant using Artyom and it was worked very well for now, but I have a problem.
I have a single command that when said, will create other commands.
Then, I have a command callback that detects when the user has finished talking., but only when the second commands are being said.
The problem is that later on, I would like to remove that callback but I don't know how to do it.
Is there any way?
