Android refreshing adapter after change rotation device

Question

in my below simple code, why my adapter can't refresh with added new data to that after change rotation device?

adding to adapter and refreshing that doesn't have any problem in first time, but after add some data to that and change device orientation.

i'm adding other data to that and i expect refresh with new added that, for example in fist time i add 1 data to adapter, the adapter can be know that and can be refresh with that, i see added data on adapter, after that, i change device orientation from for example portrait to landscape

now i add 1 data to adapter again, I expect adapter can be refresh with 2 added item.

adapter have 2 item but can't refresh with them, that have a tip:

after change orientation device adapter can be refresh with last added items

MoviesAdapter:

Movie:

public class Movie implements Parcelable {
