Why will not fill View page of this controller method

public ActionResult Person()
    {
        testEntities6 testPersons = new testEntities6();
        IQueryable<person> persons;

        DropDownLst.Items.Clear();
        DropDownLst.Items.Add("proba");

        persons = from i in testPersons.person
                  select i;
        return View(persons);
    }

and include namespaces:

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Web;
  using System.Web.Mvc;
  using System.Web.Mvc.Ajax;
  using MvcKVteam.Models;
  using System.Web.UI;
  using System.Web.UI.WebControls;
  using System.Web.UI.WebControls.WebParts;
  using System.Web.UI.HtmlControls;

In view page I put this code:

  <asp:DropDownList ID="IbekoIngDropDownLst" runat="server">
  </asp:DropDownList>
