No Keyboard in Fragment?

Currently I try to convert my Activitis to Fragments. While doing so i get multiple problems. My First and major problem is that in the SearchShop.kt no keyboard in the search texfield.
My second problem is when i try using an Emulator on my PC and using the PC keyboard i can input values but it doesn't schedule the FirebaseJob. And at last how can i add in the Fragment the functionality for the Fab Button?

SearchShop.kt
