Ok, I've solved this. The problem was that my PK was varchar and not integer
(it's a legacy database). I've managed to change it to integer and now
everything is working. Thanks!

If you're writing code and you're not testing it, the code is wrong. I don't
care if it does the right thing, and people need to understand this. If it
works by accident, you're still wrong.
