How to pass data from index view to edit view

Question

when click edit link in index page

it give me error

The model item passed into the dictionary is of type 'System.Data.Entity.DynamicProxies.Employee_2EF71CC17A29BA91B02BC5CDB0EE5AF82D363EEF7E174A21C9546772913AA929', but this dictionary requires a model item of type 'WebCourse.Models.Customemployee'.

I have custom model

namespace WebCourse.Models Customemployee
{
public class Customemployee
{
public string Name { get; set; }
public int Salary { get; set; }
public string Email { get; set; }
public int DistrictId { get; set; }

public List<EmployeeCourse> Courses { get; set; }
public List<EmployeeLangage> Langs { get; set; }
}

}

and my controller empcourse

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using WebCourse.Models;
using System.Data.Entity;
namespace WebCourse.Controllers
{
public class empcourseController : Controller
{
mycourseEntities db = new mycourseEntities();
// GET: empcourse
public ActionResult Index()
{
var query = db.Employees.ToList().Select(p => new EmpInfo
{
Id = p.Id,
Name = p.Name,
Salary = Convert.ToInt32( p.Salary),
Email = p.Email,
DistrictName = p.Destrict.DistrictName,
CityName = p.Destrict.City.CityName,
CountryName = p.Destrict.City.Country.CountryName,
CourseNames = p.EmployeeCourses.Select(t => t.Course.CourseName).ToList(),
LanguageName = p.EmployeeLangages.Select(t => t.Language.LnaguageName).ToList(),
levelName = p.EmployeeLangages.Select(t => t.Level.LevelName).ToList(),
CourseName = string.Join(",", p.EmployeeCourses.Select(t => t.Course.CourseName).ToList())
});

return View(query);
}
public ActionResult Create()
{
ViewBag.CountryId = new SelectList(db.Countries, "Id", "CountryName");
ViewBag.LanaguageId = new SelectList(db.Languages.ToList(), "Id", "LnaguageName");
ViewBag.LevelId = new SelectList(db.Levels.ToList(), "Id", "LevelName");
ViewBag.CourseId = new SelectList(db.Courses.ToList(), "Id", "CourseName");
return View();
}
public ActionResult Edit(int id)
{
//how to pass data from index view to edit view
Employee old = db.Employees.Find(id);
return View(old);
}
