Unfortunately Dictionary got always problem with Model Binding in MVC. Read the full story here. So we have to create our own custom model binder to get the Dictionary as a parameter to our controller action.

To solve your requirement, here is the working solution -

First create your ViewModels in following way. PersonModel can have list of RoleModels.

public class PersonModel
{
    public List<RoleModel> Roles { get; set; }
    public string Name { get; set; }
}

public class RoleModel
{
    public string RoleName { get; set;}
    public string Description { get; set;}
}

Then have a index action which will be serving basic index view -

    public ActionResult Index()
    {
        return View();
    }

Index view will be having following JQuery AJAX POST operation -

<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
    $(function () {
        $('#click1').click(function (e) {

            var jsonObject = {
                "Name" : "Rami",
                "Roles": [{ "RoleName": "Admin", "Description" : "Admin Role"}, { "RoleName": "User", "Description" : "User Role"}]
            };

            $.ajax({
                url: "@Url.Action("AddUser")",
                type: "POST",
                data: JSON.stringify(jsonObject),
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                error: function (response) {
                    alert(response.responseText);
            },
                success: function (response) {
                    alert(response);
                }
            });

        });
    });
</script>

<input type="button" value="click1" id="click1" />

Index action posts to AddUser action -

    [HttpPost]
    public ActionResult AddUser(PersonModel model)
    {
        if (model != null)
        {
            return Json("Success");
        }
        else
        {
            return Json("An Error Has occoured");
        }

    }

So now when the post happens you can get all the posted data in the model parameter of action.
