my VM:

 private ObservableCollection<LanguageSelector> _languages;

 public ObservableCollection<LanguageSelector> Languages
 
 get return _languages;

  You need raise event PropertyChanged for property Languages

  You should call OnPropertyChanged("SLanguage"); in set property of SLanguage and set SelectedItem="Binding Path=SLanguage, Mode=TwoWay, UpdateSourceTrigger=OnPropertyChanged".
