How do I create an object at every copy of another object

Quite a simple little thing but I can't seem to figure out how to do it.

Basically what I'm trying to do is have an object, in this case let's say it's an enemy with a gun, fire a bullet every X amount of seconds.

This works fine... when there's only one instance of this enemy. When I copy that enemy it only creates a new bullet at the first created enemy while the rest do nothing.

How would I go about making sure that it creates a new bullet at every copy of that enemy which I place in my levels?

Your Events sheet at least must looks like this:

Each enemy copy is shooting altogether.
