notifyPropertyChanged of DataBinding is not working in below code. I executed notifyPropertyChanged, but it did not change view. The below code was working in 2.2.3.

* DataModel

```
public class User extends BaseObservable {
    private static final String TAG = User.class.getSimpleName();

    private String name;

    @Bindable
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;

        // not working in 2.3.0
        notifyPropertyChanged(BR.name);
    }

    public void changeName(String name) {
        Log.d(TAG, "changeName");
        setName(name);
    }
}
```

* ViewModel

```
public class ViewModel extends BaseObservable {
    public final ObservableField<User> user = new ObservableField<>();

    ViewModel() {
        User user = new User();
        user.setName("Name");
        this.user.set(user);
    }

    public void onClickButton(View view) {
        user.get().changeName("Change name");
    }

}
```

* Layout XML

```
<layout>

    <data>

        <variable
            name="viewModel"
            type="com.star_zero.example.checkbug.ViewModel" />
    </data>

    ...

     <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@{viewModel.user.name}" />  

    ...

</layout>
```


If using getter/setter(@bindable) instead of ObservableField in ViewModel, It is working.

I attached a project file to reproduce.
