have you enabled the passive checks in the nagios.cfg ?
by default is it set to 0 - which is disabled
accept_passive_service_checks=0


also have you enabled external commands :
check_external_commands=1

also to help to debug it more you may want to the options:
log_external_commands=1
log_passive_checks=0

plus - have the nagios.debug file enabled - and make sure to add the 
external commands to the output - that might give you more information.
