Change object target on same ObjectBehaviour at runtime

Hi,

I'd like to change the object target at runtime on a same ObjectBehaviour in Unity. Is this possible?

Thanks in advance and have a nice day!

EDIT: I noticed that even setting another object target from editor on the same ObjectBehaviour seems to not change the target correctly. In my case I have two image targets A and B in the database, but no matter which I select, the logs always tell me that the target B is loaded, even if I select A in editor.
