Collision in a static mesh created with the construction script

Hi i’ve created a cube with a construction script with the node addStaticMeshcomponent. There is some movement associated with it. I used a pawn blueprint. When i play the game collisions are not effective. But if i create the cube directly in the component tabs, collisions are effective. Haw can i enabled the collision with this addstaticmeshcomponent ?

So nobody has this problem.
I’ve tried all i can but if the mesh is created by the node add static mesh then i didn’t have any collision …
