Xamarin CarPlay InformationTemplate Custom Back Button Handle Problem

Our xamarin forms project supported CarPlay and has a information template. I want to use custom back button on information template but when user click back button, handle section is not calling.

Back button create function codes:

private CPBarButton GetBackButton()
        {
            return new CPBarButton("Back", handler =>
            {
                try
                {
                    if (interfaceController != null && interfaceController.Templates != null && interfaceController.Templates.Length > 1)
                    {
                        interfaceController.PopTemplate(true);
                    }
                }
                catch { }
            });
        }
