Go read the manual. The example is based on categories, but changing it to custom taxonomies should not be a problem.

I posted this question before discovering that the hook does not work properly.So, I guessed it was because of me using taxonomies.

Yeah, I noticed it was you, but I answered here as well to benefit others reading the forums…
