Missing controller actions from plugin

I am having a problem in that the url
/map/del_selected_geo give me an error

Unknown action
No action responded to del_selected_geo. Actions: get_links and index

but if I go into console it seems to be there:

ctl = MapController.new

That method was added inside of a plugin where this source is included
via require() in init.rb:
The module GeoHelper defines del_selected_geo()

require ‘geo_helper’

class ActionController::Base
include GeoHelper
helper :geomap


After that I also have:

ActionController::Base.class_eval do
path = File.join(File.dirname(FILE), ‘app/views’)


extend GeoCtlClass


I’m sort of puzzled on that …could the
helper :geomap
throw it off which is stuff for the view ?
GeoHelper is controller related …
