Upper windshield trim is loose

[SK101]

The black trim above the windshield occasionally comes loose on the passengers side. But not at the end, that stays connected and the trim forms a bow between the center and the end. I push it back and it seems to fit and stays in place for a few weeks.
What is supposed to hold it in place? Maybe im missing clips or something?

When it is pulled away/loose and you can safely pull it to make a little room, clean thoroughly with alcohol and use some water sealer, very thin film, and push back in place. Do this when you can push in place and let sit for a couple days in a dry place.

Or, ask a glass business the best thing to do.
