To invoke PropertyChanged just call OnPropertyChanged in the setter of your property 

bool _isLoaded;

public bool IsLoaded
{
    get { return _isLoaded; }
    set
    {
        _isLoaded = value;
        OnPropertyChanged(nameof(IsLoaded));
    }
}

protected void OnPropertyChanged (string name)
{
    PropertyChanged?.Invoke (this, new PropertyChangedEventArgs (name));
}
