delphi - オブジェクトを TListView にバインドする

Question

私は最近 を発見し、Delphiに関するこの素晴らしいチュートリアルData Bindingsに従いました。で動作させましたが、今は があり、それらをバインドすることができましたが、一方向でしか動作しません。my を変更すると が変更されますが、: を変更しても は変更されません。data bindingTEditTObjectListTObjectListListViewListViewTOBjectList

これが私のコードです：

// When I change an Item of my ListView
procedure TForm1.ListView1Change(Sender: TObject; Item: TListItem;
  Change: TItemChange);
begin
  TBindings.Notify(Sender, 'Items.Item[' + IntToStr(Item.Index) +   '].Caption');
end;

// When I add a new item to my TListView, and I want that to be bound with my ListView
itemAdd := ListView1.Items.Add;
Item.Bind('id', ListView1, 'Items.Item[' + IntToStr(ListView1.Items.Count-1) + '].Caption');



  // The TBoundObject Class. Every class thatI want to bind with UI, inherits from this class
  unit U_TBoundObject;

  interface

  uses
    Generics.Collections, System.Bindings.Expression, System.Bindings.Helper;

  type
    TBoundObject = class
    protected
      type
        TExpressionList = TObjectList<TBindingExpression>;
    private
      FBindings: TExpressionList;
    protected
      procedure Notify(const APropertyName: string = '');
      property Bindings: TExpressionList read FBindings;
    public
      constructor Create; virtual;
      destructor Destroy; override;
      procedure Bind(const AProperty: string; const ABindToObject: TObject;
          const ABindToProperty: string; const ACreateOptions:
          TBindings.TCreateOptions = [coNotifyOutput, coEvaluate]);
      procedure ClearBindings;
    end;

  implementation

  constructor TBoundObject.Create;
  begin
    inherited;
    FBindings := TExpressionList.Create(false {AOwnsObjects});
  end;

  destructor TBoundObject.Destroy;
  begin
    ClearBindings;
    FBindings.Free;
    inherited;
  end;

  procedure TBoundObject.ClearBindings;
  var
    i: TBindingExpression;
  begin
    for i in FBindings do
      TBindings.RemoveBinding(i);
    FBindings.Clear;
  end;

  procedure TBoundObject.Notify(const APropertyName: string);
  begin
    TBindings.Notify(Self, APropertyName);
  end;

  procedure TBoundObject.Bind(const AProperty: string;
    const ABindToObject: TObject; const ABindToProperty: string;
    const ACreateOptions: TBindings.TCreateOptions);
  begin
    // From source to dest
    FBindings.Add(TBindings.CreateManagedBinding(
        { inputs }
        [TBindings.CreateAssociationScope([Associate(Self, 'src')])],
        'src.' + AProperty,
        { outputs }
        [TBindings.CreateAssociationScope([Associate(ABindToObject, 'dst')])],
        'dst.' + ABindToProperty,
        nil, nil, ACreateOptions));
    // From dest to source
    FBindings.Add(TBindings.CreateManagedBinding(
        { inputs }
        [TBindings.CreateAssociationScope([Associate(ABindToObject, 'src')])],
        'src.' + ABindToProperty,
        { outputs }
        [TBindings.CreateAssociationScope([Associate(Self, 'dst')])],
        'dst.' + AProperty,
        nil, nil, ACreateOptions));
  end;

  end.
