Sudoers, allow user to use root alias

Question

Actually, my root have to aliases:

alias unpool='/path/to/my/scripts/unpool.sh' alias pool='/path/to/my/scripts/pool.sh' 

I have the same for my user in ~/.bashrc

I defined my /etc/sudoers.d/user with

user ALL=(root) NOPASSWD: /bin/cp user ALL=(root) NOPASSWD: /path/to/my/scripts/pool.sh user ALL=(root) NOPASSWD: /path/to/my/scripts/unpool.sh 

But logged with my user, I can't do sudo unpool, it ask me my password

What can I do ?
