ruby on rails - perform not being called for Delayed Jobs -

i'm using delayed_job 2.1.4 collectiveidea, , seems perform method never called though jobs processed , removed queue. missing something?

i'm using rails 3.0.5 on heroku

in controller:

delayed::job.enqueue facebookjob.new 

in job class:

class facebookjob   def initialize   end    def perform     fb_auths = authentication.where(:provider => 'facebook')     fb_auths.each |auth|       checkins = fbgraph::user.new('me', :access_token => uri.encode(auth.token)).checkins       if checkins != nil          checkins.each |checkin|           [...]         end       end     end   end end
