How can i edit multiple SQL Tables in a View in MVC 4 with using Razor engine?

In my SQL, There are two table which I want to edit on my MVC 4 project. Both of them has content like:

id   Title   Description
1    title1  desc1
2    title2  desc2
.    .       .
.    .       .

I tried to get them in a View to edit both table in same time. Model of table1:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;

namespace emirhanozkan.Models
{
public partial class PersonInfo
{
    [Key]
    public int id { get; set; }

    public string Title { get; set; }

    public string Description { get; set; }
}
}

Model of table2 has same content only class name is Profile.

Then, set them as list in other class like:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using emirhanozkan.Models;

namespace emirhanozkan.Models
{

    public class AllProfile
    {
        emirhanozkanContext db = new emirhanozkanContext();
        public List<PersonInfo> ListPersonInfo { set; get; }
        public List<Profile> ListProfile { set; get; }
    }
}

My controller is:

public ActionResult EditProfileInfo()
        {
            var nl = new AllProfile();
            nl.ListPersonInfo = db.PersonInfoes.ToList();
            nl.ListProfile = db.Profiles.ToList();
            return View(nl);
        }
        [HttpPost]
        public ActionResult EditProfileInfo(AllProfile allprofile)
        {
            db.Entry(allprofile).State = System.Data.EntityState.Modified;
            foreach (var item in allprofile.ListPersonInfo)
            {
                db.PersonInfoes.Where(x => x.id == item.id);
                db.PersonInfoes.Where(x => x.Title == item.Title);
                db.PersonInfoes.Where(x => x.Description == item.Description);
            }
            foreach (var item in allprofile.ListProfile)
            {
                db.Profiles.Where(x => x.id == item.id);
                db.Profiles.Where(x => x.Title == item.Title);
                db.Profiles.Where(x => x.Description == item.Description);
            }
            db.SaveChanges();
            return RedirectToAction("ProfileInfo");
        }

My View is:

@model emirhanozkan.Models.AllProfile

@{
    ViewBag.Title = "EditProfileInfo";
}

<h2>EditProfileInfo</h2>

@using (Html.BeginForm(null, null, FormMethod.Post)) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    <fieldset>

        <legend>PersonInfo</legend>
        @foreach (var item in Model.ListPersonInfo)
        {
            @Html.HiddenFor(model => item.id)
            <div class="editor-field">
                @Html.EditorFor(model => item.Title)
                @Html.ValidationMessageFor(model => item.Title)
            </div>
            <div class="editor-field">
                @Html.EditorFor(model => item.Description)
                @Html.ValidationMessageFor(model => item.Description)
            </div>
        }
        @foreach (var item in Model.ListProfile)
        {
            @Html.HiddenFor(model => item.id)
            <div class="editor-field">
                @Html.EditorFor(model => item.Title)
                @Html.ValidationMessageFor(model => item.Title)
            </div>
            <div class="editor-field">
                @Html.EditorFor(model => item.Description)
                @Html.ValidationMessageFor(model => item.Description)
            </div>
        }

        <p>
            <input type="submit" value="Save" />
        </p>
    </fieldset>
}

When I press the edit button db.Entry(allprofile).State = System.Data.EntityState.Modified; has an error like:

An exception of type 'System.InvalidOperationException' occurred in EntityFramework.dll but was not handled in user code
Additional information: The entity type AllProfile is not part of the model for the current context.

My you help me to edit these tables in a View?
