Get checkbox values in controller mvc 4

I am trying to retrieve the checked checkbox value from a checkbox list without any success , below is the code which i have tried:

Model

 [DisplayName("Gender")]
    public IList<SelectListItem> Gender { get; set; }

Controller

 public ActionResult Index()
        {
            AssociateFormViewModel objStudentModel = new AssociateFormViewModel();

            List<SelectListItem> genderNames = new List<SelectListItem>();
            genderNames.Add(new SelectListItem { Text = "Male", Value = "1" });
            genderNames.Add(new SelectListItem { Text = "Female", Value = "2" });
            genderNames.Add(new SelectListItem { Text = "Prefer not to say", Value = "3" });

            objStudentModel.Gender = genderNames;
            return PartialView("AssociateApplicationForm", objStudentModel);

        }

[HttpPost]
        public ActionResult HandleFormSubmit(MembershipFormViewModel model)
        {
            //model not valid, do not save, but return current umbraco page
            if (ModelState.IsValid == false)
            {
                return CurrentUmbracoPage();
            }
 string test = "Gender: " + model.Gender + Environment.NewLine; //getting null here
 return RedirectToCurrentUmbracoPage();
}

View

@foreach (var names in @Model.Gender)
                {
                var checkBoxId = "chk" + names.Value;
                var tdId = "td" + names.Value;
                    <table width="100%">
                        <tr >
                            <td width="20px">
                                <input type="checkbox" id="@checkBoxId" class="chkclass" value="@names.Value" />
                            </td>
                            <td id="@tdId"  width="100px">
                                @names.Text
                            </td>
                        </tr>
                    </table>

assign a name to your checkbox:

<input name="gender" type="checkbox" id="@checkBoxId" class="chkclass" value="@names.Value" />

Then accept a string array of with parameter name gender

[HttpPost]
        public ActionResult HandleFormSubmit(string[] gender,
             MembershipFormViewModel model)
        {
            //model not valid, do not save, but return current umbraco page
            if (ModelState.IsValid == false)
            {
                return CurrentUmbracoPage();
            }
            string test = "Gender: " + model.Gender + Environment.NewLine; //getting null here
            return RedirectToCurrentUmbracoPage();
        }
