You'll require to notify observer when you set value like this :

public class UserData extends BaseObservable{
private String firstName ;
@Bindable
public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
    notifyPropertyChanged(BR.firstName) // call like this
}
}
