Solved CanEquipItem hook not working

Tried to call hook, which can be found in docs.

Code:

void CanEquipItem(PlayerInventory inventory, Item item)
{
Puts("CanEquipItem works!");
}

Nothing happens, when i take things to\from belt, inventory or arms.
Is that hook still actual?

 

But now it doesn't (for me). I tried the code above - nothing happens
