Обновление данных в фрагменте с помощью Navigation Architecture Component

Пытаюсь сделать, так чтобы после выбора города в AutoCompleteSearchView(данный компонент я определил в MainActivity), который кладу в Bundle и передаю во фрагмент, где необходимо выполнить новый запрос и обновить данные во фрагменте, но этого не происходит. Или это необходимо реализовать как-то по другому? Так же пытался сделать с помощью Sharedpreferences, получал Nullpointerexception, когда вызывал стандартным способом фрагмент(getsupportfragmentmanager).

MainActivity:

public class MainActivity extends AppCompatActivity {
@BindView(R.id.bottom_nav)
BottomNavigationView bottom_nav;
@BindView(R.id.toolbar)
Toolbar toolbar;
private NavController navController;
private AutoCompleteSearchView searchView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(this);
    setSupportActionBar(toolbar);
    navController = Navigation.findNavController(this, R.id.nav_host_fragment);
    NavigationUI.setupWithNavController(bottom_nav, navController);
    NavigationUI.setupActionBarWithNavController(this, navController);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.search_menu, menu);
    MenuItem searchViewItem = menu.findItem(R.id.action_search);
    searchView = (AutoCompleteSearchView) searchViewItem.getActionView();
    searchView.setUseDefaultProgressBar(true);
    searchView.setOnPredictionClickListener((position, prediction) -> {
        Bundle bundle = new Bundle();
        bundle.putString("city", prediction.displayString);
        navController.navigate(R.id.currentWeatherFragment, bundle);
        searchViewItem.collapseActionView();
    });
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            return true;
        }
        @Override
        public boolean onQueryTextChange(String newText) {
            if (newText.length() >= 3) {
                searchView.showProgressBar();
                NetworkPredictions(newText);
            }
            return true;
        }
    });
    return true;
}
private void NetworkPredictions(String newText) {
    ServiceGenerator serviceGenerator = ServiceGenerator.getInstance();
    Call<List<CityWeatherResponse>> call = serviceGenerator.getApi().getCity(newText);
    call.enqueue(new Callback<List<CityWeatherResponse>>() {
        @Override
        public void onResponse(Call<List<CityWeatherResponse>> call, Response<List<CityWeatherResponse>> response) {
            if (response.isSuccessful() && response.body() != null) {
                List<CityWeatherResponse> rawPredictions = new ArrayList<>();
                rawPredictions.addAll(response.body());
                List<Prediction> predictions = toSearchViewPredictions(rawPredictions);
                searchView.applyPredictions(predictions);
                searchView.hideProgressBar();
            }
        }
        @Override
        public void onFailure(Call<List<CityWeatherResponse>> call, Throwable t) {
        }
    });
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            navController.popBackStack();
            return true;
    }
    return super.onOptionsItemSelected(item);
}
private List<com.amsen.par.searchview.prediction.Prediction> toSearchViewPredictions(List<CityWeatherResponse> predictions) {
    List<Prediction> forSearchView = new ArrayList<>();
    for (CityWeatherResponse prediction : predictions) {
        forSearchView.add(new Prediction(prediction, prediction.name));
    }
    return forSearchView;
}}
