[E-devel] how can evas to bring first

Hello, I use wayland and want to develop with EFL for study, I active weekeyboard and it show virtualkeyboard successfully, but the keyboard evas is below the open window, so when the window is maximum or put down part screen, the virtualkeyboard should not been seen, how can I raise the window to toplevel?
I tried use ecore_evas_raise but it had no effect, looks not fn_raise implementation, and tried use ecore_wl2_window_type_set(wkb->win, ECORE_WL2_WINDOW_TYPE_TOPLEVEL); but the process died! How can I do that? Thanks.
