Is it a bug in Umbraco 7 ? I can catch media service event when I click save button. But does not work for localization service ? Is there any way to catch event when user save or delete dictionary item.

Thank you so much

public class RegisterEvents : ApplicationEventHandler
{
    public RegisterEvents()
    {
        MediaService.Saved += new TypedEventHandler>(MediaServiceSaved);
        LocalizationService.SavedDictionaryItem += new TypedEventHandler>(DictionaryServiceSaved);
    }
    void MediaServiceSaved(IMediaService sender, SaveEventArgs e)
    {
        foreach (var mediaItem in e.SavedEntities)
        {
            // Do whatever you want with each entity
        }
    }
    void DictionaryServiceSaved(ILocalizationService sender, SaveEventArgs e)
    {
        foreach (var dicItem in e.SavedEntities)
        {
            // Do whatever you want with each entity
        }
    }
}
