Why my name from CartOrderViewModel dont sent to method Test from index View ?

ASP.NET binds to properties, not fields. Change all of the public fields in class CartOrderViewModel to be mutable properties with { get; set; }.

Like so:

public class CartOrderViewModel
{
    public Cart?   Carts  { get; set; }
    public Order?  Orders { get; set; }
    public String? Name   { get; set; }
}

Don't forget to add validation attributes, such as [Required], as per your project's needs.
