Hi Leo,

We have uploaded the hotfix for CROS-798 featuring CommandProperty binding support to UIButton in custom UICarouselVewCell. 

You can download the nightly build here. Please note that you need to use Unified API for it to work, also please mind that you need to add these code because how the UIButton work differently in iOS for ViewSlider. Just add the Bolded code below, i use the View Slider samples as the example:

[ImportBinding(typeof(ItemSliderBindingProvider))]    public partial class ItemSliderViewController : UIViewController<ItemSliderViewModel>,ISupportItemBinding    
{        

private Dictionary<Type, IItemBindingAdapter> _itemBindingAdapters = null;

        public UICarouselView CarouselView { get; set; }

        public ItemSliderViewController()
        {
        }

        #region ISupportItemBinding implementation

        public Dictionary<Type, IItemBindingAdapter> ItemBindingAdapters
        {
            get
            {
                if (_itemBindingAdapters == null)
                    _itemBindingAdapters = new Dictionary<Type, IItemBindingAdapter>();

                return _itemBindingAdapters;
            }
        }
        #endregion

        protected override void OnViewInitialized()
        {
            base.OnViewInitialized();

            //register the binding adapter for UIButton
            this.ItemBindingAdapters.Add(typeof(UIButton), Activator.CreateInstance<UIButtonItemBindingAdapter>());

            this.Title = "Custom Template";
        }

        protected override void InitializeView()
        {
            base.InitializeView();

            this.EdgesForExtendedLayout = UIRectEdge.None;

            this.CarouselView = new UICarouselView(new CGRect(0, 0, this.View.Bounds.Width, this.View.Bounds.Height))
            {
                AutoresizingMask = UIViewAutoresizing.FlexibleDimensions,
                CellTemplate = new UIViewTemplate(ItemSliderCellView.Nib)
            };
            this.View.AddSubview(this.CarouselView);

            this.RegisterViewIdentifier("ViewSlider", this.CarouselView);
        }

        protected override void Dispose(bool disposing)
        {
            base.Dispose(disposing);

            if (disposing)
            {
                this.ItemBindingAdapters.Clear();
            }
        }
    }

Best Regards
