If this is in a script run by mod_ruby or eruby, then it may be that you 
are actually creating a different CGI class in a anonymous module.

On the other hand, if its run like a regular CGI script, I don't think 
this should be a problem.

Have you tried inheriting from the CGI class instead?
   class MyCGI < CGI
     def checkbox # etc
     end
   end

Another option is to put your method definitions in a module and 
extending your actual CGI object dynamically...

   module MyCGIExt
     def checkbox # etc
     end
   end
   cgi = CGI.new
   cgi.extend MyCGIExt

These last two should work properly in a mod_ruby/eruby environment, 
AFAIK. HTH.
