adding open action to other objects

I noticed that objects such as microwave and cabinets have the action of opening, and I would love to add this open actions on other objects, such as doors. Right now I added the simobj id for the door, attached the door script to the door object, and tried to include the door simtype as part of the open_close state objects, but when I run the simulator and try to open the door, it doesn't work. Is there a way to make this happen?
