How to create additional start up script for one service

Question

I installed the package 'gearman-job-server' in Ubuntu server. it creates start up script by default as /etc/init/gearman-job-server.conf. But I want to add more command to same service. So created my custom start script as /etc/init/gearmand.conf, with below content. But unfortunately it's not running, when I restart the service (service gearman-job-server restart). So can someone tell me how to hook the custom start up script to the same service.
