Do you have 'event_handler_enabled 1' in your local-service template?
You need it either there or in this definition. Enabling event handlers
in nagios.cfg isn't sufficient. You need to tell nagios which services
it should actually run them for.

You really should follow the documented methodology for event handlers
(http://nagios.sourceforge.net/docs/2_0/eventhandlers.html). I'm not
sure the above is going to work and if it does, it will attempt to
restart httpd on any kind of status change, even WARNING -> OK. I'm sure
that you don't want that. Additionally, if you follow the documented way
you can easily send debugging output to a file so that you can see if
your event handler is being run, how and what it's doing.
