How to create any widget dynamically and add it to the list view

So I have a custom UGameInstance called gameInstance.

I also have a BlueprintCallable method where I can set my custom C++ list of objects that looks like following:

void AMyActor::SetLists(UListView* l)
{
	auto callback = [this, l](MyObjectList* list)
	{
		for (auto& item : list->GetItems())
		{
			gameInstance->GetList(&item);
			FString name = item.GetName();
			UMyExtendedWidget* row = NewObject<UMyExtendedWidget>();
			row->AddText(name);
            // set other data here
			l->AddItem(row);
		}
	};

	gameInstance->GetLists(callback);
}

And I have my UMyExtendedWidget which is a widget I had to extend because I have multiple components in a single row (two buttons, image, and a text, in the blueprint designer they are all under horizontal box component), and it looks like following:

UCLASS(BlueprintType, Blueprintable)
class QUICKSTART_API UMyExtendedWidget : public UUserWidget
{
	GENERATED_BODY()
	
public:
	UMyExtendedWidget(const FObjectInitializer& ObjectInitializer);

	void AddText(FString name)
	void AddButtonOne(FString url);
	void AddButtonTwo(FString url);
	void AddImage(FString url);


public:
	virtual void NativeConstruct() override;

	UPROPERTY(BlueprintReadWrite, meta = (BindWidget))
		UButton* MyButtonOne;

	UPROPERTY(BlueprintReadWrite, meta = (BindWidget))
		UButton* MyButtonTwo;

	UPROPERTY(BlueprintReadWrite, meta = (BindWidget))
		UImage* MyImage;

	UPROPERTY(BlueprintReadWrite, meta = (BindWidget))
		UTextBlock* MyLabel;
};

Which I all placed under HorizontalBox in the UI of UMyExtendedWidget in the blueprint.

However, UMyExtendedWidget::NativeConstruct gets called one or more frames after call to AMyActor::SetLists and the data I set through AMyActor::SetLists never get to be rendered.
Is there a way to avoid this? What are my options?
