307 trunk lock problem ..

Good night, 2 days ago I had the 2002 model 1.6 xs, thank goodness. There is a problem in my car, but ..
When I put my hand on the trunk release while the car is locked, I naturally see that the trunk is locked. Everything is normal until now. It doesn't happen when I don't rub my hand on the episode.
Is it a problem I mentioned above or is it normal? What are the steps I need to do for Sroun solution?
07 im is my first car so i can't understand the cars for now. I would be glad if you could help ..

The lock of the vehicle remains stuck. The button inside the lock that is powered can remain stuck.
