Rails - Dec 2013 - reset_authentication_token! method not being called but reset_authentication_token_! can be called

I am having problems calling a method reset_authentication_token! . if i 
just leave the method as it is with the ! behind it the method is simply 
ignored when the program is run (none of the logger methods inside the 
method is called.) But if i add any other character into it the method gets 
called

Below is the module of the methods. 
This module is included in user.rb

The module auth_token.rb
http://pastie.org/8563575

The user.rb

http://pastie.org/8563585

This is the session_controller.rb file

http://pastie.org/8563578

The reset_authentication_token! is called from the main create method which 
calls the @user.ensure_authentication_token!
