No parameterless constructor defined for this object in ASP.NET MVC

I am getting No parameterless constructor defined for this object error while posting data. It is working fine on get. I am using service pattern in my project and using unity container for handling dependency injection. I have registered all the services in container.

Stack Trace :-

As suggested in some articles i have also created the constructor for my model but no luck.

My Controller (GET)

    [HttpGet]
    public ActionResult Home()
    {
        var ct = _ctService.getctdetails();

        var viewModel = new HomeviewModel()
        {
            itemsList= GetItemsList(),
            ctDTO= ct 

        };
        return View(viewModel);
    }

POST:-

    [HttpPost]
    public ActionResult Submit(HomeviewModel values)
    {


        return RedirectToAction("Index");
    }

ViewModel:-

  public class HomeviewModel
 {
    public productDetailsDTO { get; set; }
    public CreationDTO ctDTO{ get; set; }
    public SelectList itemsList{ get; set; }
  }

Controller Constructor

 public HomeController(ICTService ctService,
        ITemsService itemService)
    {
        _ctService= ctService;
        _itemService= itemService;
    }

In My view i am just using the itemslist and setting values in DTO , fetching some data using ajax if we change the selected item and submitting form, the control is coming to the controller constructor but after that giving error,not going to the post method.
