to customize link_to

Hi I''m trying to customize the link_to helper and keep getting this
error,
any suggestion how can I work arround it?

this is the error message:

undefined method `link_to'' for module `UserHelper''


this is my users_helper.rb:

module UsersHelper

  alias_method :link_to_original, :link_to
  alias_method :link_to, :link_to_permission


def link_to_permission(name, options = {}, html_options = nil,
*parameters_for_method_reference)
  if @permission
    if html_options
          html_options = html_options.stringify_keys
          convert_options_to_javascript!(html_options)
          tag_options = tag_options(html_options)
        else
          tag_options = nil
        end
        url = html_escape(options.is_a?(String) ? options : url_for(options,
*parameters_for_method_reference))
        "<a
href_1234=\"#{url}\"#{tag_options}>#{name||url}</a>"
else
	link_to_original( name, options,
html_options,*parameters_for_method_reference )
end

end

end

>   alias_method :link_to_original, :link_to
Isn''t it:

alias link_to_original link_to

or the other way around:

alias link_to link_to_original

but no commas, and no :interns
