Interior cladding of the car door loosely, how can you fix it again?

Good day, a short time ago I bought an old VW Lupo. Now I noticed that the interior cladding of the driver’s door loosened up on one side and a piece stands off. Before that it was stuck there with some white glue. This had dissolved. I removed the rest. I then tried to glue the part with hot glue, but also this held just 1 day. Does anyone know how (with which material) it can be glued on, so it holds for sure?
