I have model Home

public class HomeViewModel
 {
    public string Title { get; set; }
    public string Description { get; set; }
    public string MetaTitle { get; set; }
    public virtual IEnumerable<CarouselItem> Carousel { get; set; }
 }

I have Carouse model

  public class CarouselItem
    {
        public string Image { get; set; }
        public string Title { get; set; }    
        public string Text { get; set; }
    }

My mapper configs

HomeMap

 public class HomeMap : UmbMapperConfig<HomeViewModel>
 {
     public HomeMap()
     {
         this.AddMap(item => item.Title);
         this.AddMap(item => item.MetaTitle);
         this.AddMap(item => item.Description);
         this.AddMap(item => item.Carousel).SetMapper<ArchetypeFactoryPropertyMapper>();
     }
 }

and CarouselMap

public class CarouselMap : UmbMapperConfig<CarouselItem>
{
    public CarouselMap()
    {
        this.AddMap(item => item.Image).SetMapper<UmbracoPickerPropertyMapper>();
        this.AddMap(item => item.Title);
        this.AddMap(item => item.Text);
    }
}

My Action where I make map

public override ActionResult Index(RenderModel model)
{
    var viewModel = model.Content.MapTo(typeof(HomeViewModel));

    return CurrentTemplate(viewModel);
}

But for Carousel I get null in list

Could you explain me, what I should to do wrong?
