Mehh.... Evil... A look at the documentation says how to do it:

http://api.rubyonrails.com/classes/ActionView/Helpers/FormHelper.html#M000344

*check_box*(object, method, options = {}, checked_value = "1", 
unchecked_value = "0")

Returns a checkbox tag tailored for accessing a specified attribute 
(identified by method) on an object assigned to the template (identified 
by object). It's intended that method returns an integer and if that 
integer is above zero, then the checkbox is checked. Additional options 
on the input tag can be passed as a hash with options. The checked_value 
defaults to 1 while the default unchecked_value is set to 0 which is 
convenient for boolean values. Usually unchecked checkboxes don't post 
anything. We work around this problem by adding a hidden value with the 
same name as the checkbox.

So your category_id seems to be in the wrong place.
