How to make a note with box in JLink??

Hi Everyone, I‘m a newcomer in JLink, so I have occurred a lot of problems during developing, but there is a little problem which I have not idea how to fix. This problem is about making customize note with box in drawing, but I cannot make note success in a box with leader. Just see my code following:

public static void setNoteDetail(Session session, Selection sel) throws jxthrowable {
		Model currentModel = session.GetCurrentModel();
		WoodSelection woodSel = new WoodSelection();
		Window win = session.GetCurrentWindow();
		win.Activate();
		if(currentModel.GetType() != ModelType.MDL_DRAWING) {
			return;
		}
		Drawing currentDrawing = (Drawing) currentModel;
		
//		font definition

		DetailText detailText = pfcDetail.DetailText_Create("@[123@]");
		DetailTexts detailTexts = DetailTexts.create();
		AnnotationTextStyle anotationTextStyle = pfcDetail.AnnotationTextStyle_Create();
		
		anotationTextStyle.SetHeight(3.5);
		detailText.SetTextStyle(anotationTextStyle);
		detailTexts.set(0, detailText);
		
		DetailTextLine detailTextLine = pfcDetail.DetailTextLine_Create(detailTexts);
		DetailTextLines detailTextLines = DetailTextLines.create();
		
		detailTextLines.set(0, detailTextLine);
		
		
		View2D view = sel.GetSelView2D();
		Point3D point = sel.GetPoint();
		Transform3D transformMatrix = view.GetTransform();
		point = transformMatrix.TransformPoint(point);
		
		FreeAttachment freeAttachment = pfcDetail.FreeAttachment_Create(point);
		freeAttachment.SetView(view);
		
		DetailNoteItem detailNoteItem = currentDrawing.CreateFreeNote(detailTextLines, freeAttachment);
		
//		arrow definition

		ParametricAttachment leaderParaAttachment = pfcDetail.ParametricAttachment_Create(sel);
		LeaderAttachment leaderAttachment = pfcDetail.LeaderAttachment_Create(leaderParaAttachment);
		LeaderAttachments leaderAttachments = LeaderAttachments.create();
		leaderAttachments.set(0, leaderAttachment);

		detailNoteItem.SetLeaders(leaderAttachments);

		detailNoteItem.Show();
		detailNoteItem.IsDisplayed();
	}

Well, I got result with this code just see the picture, the note without box,

I do not know why , how to input text in JLink can CreO display note with box??
