Collision between 2 objects is not working?

I have a basic space shooting game in Unity 5 and I’m trying to make the spaceship get destroyed when the laser collides with it. The spaceship has a kinematic rigidbody and a non-trigger collider. The laser has a non-kinematic rigidbody and a trigger collider. When I place the laser just ahead of the spaceship so that they will collide, it works. But if I duplicate the laser using Instantiate, and then the duplicate collides with the spaceship, nothing happens.

Save the laser as a prefab, then duplicate that.

I tried that already and it still was not colliding
