Unable to get data in view using data-binding in custom dialog - Android

Question

Unable to populate data in view using data binding. In normal method(findViewById), Data is populating but after added binding data is not appear.

Dialog Class: This is my dialog class

public class MapPopUpWindow {
    MapPopWindowBinding mapPopWindowBinding;
    String locationName;
    String restaurantName;

    public void DialogMenu(Context context, Bundle bundle) {
        getDataFromBundle(bundle);
        Dialog dialog = new Dialog(context, R.style.DialogTheme);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        mapPopWindowBinding = (MapPopWindowBinding) DataBindingUtil.inflate(LayoutInflater.from(context), R.layout.map_pop_window, null, false);
        dialog.setContentView(mapPopWindowBinding.getRoot());
        mapPopWindowBinding.executePendingBindings();
        Objects.requireNonNull(dialog.getWindow()).setGravity(Gravity.BOTTOM);
        dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
        dialog.show();
    }

    private void getDataFromBundle(Bundle bundle){
        locationName = bundle.getString("location_name");
        restaurantName = bundle.getString("restaurant_name");
    }

    public String setLocationName(){
        return locationName;
    }

    public String setRestaurantName(){
        return restaurantName;
    }
}

Dialog is not properly showing when set using binding and it works with normal way Xml : Here added data tag

            android:text="@{mapViewModel.setRestaurantName()}"/>

    </androidx.constraintlayout.widget.ConstraintLayout>
</layout>
