ASP.NET MVC jQuery Post Error

I'm trying to create a simple MVC App to insert data into a db using AJAX Post method and am getting an unhandled exception error. I structured the code identical to the tutorial page, so I am having some trouble figuring out where the error is coming from. Not sure if I possibly need to modify the sql connection. Any help is appreciated. Thanks!

Model:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace MvcAjax.Models
{
public class Employee
{
public string Name { get; set; }
public string City { get; set; }
public string Address { get; set; }
}
}

View:
@{
ViewBag.Title = "AddEmployee";
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>

$(document).ready(function () {
//function will be called on button click having id btnsave
$("#btnSave").click(function () {
$.ajax(
{
type: "POST", //HTTP POST Method
url: "Home/AddEmployee", // Controller/View
data: { //Passing data
Name: $("#txtName").val(), //Reading text box values using Jquery
City: $("#txtAddress").val(),
Address: $("#txtcity").val()
}

});

});
});

</script>
<br /><br />
<fieldset>
<div class="form-horizontal">
<div class="editor-label">
Name
</div>
<div class="editor-label">
<input type="text" id="txtName" />
</div>

<div class="editor-label">
Address
</div>
<div class="editor-label">
<input type="text" id="txtAddress" />
</div>

<div class="editor-label">
City
</div>
<div class="editor-label">
<input type="text" id="txtcity" />
</div>
<div class="editor-label">
<br />
<input class="btn-default" type="button" id="btnSave" value="Save" />
</div>
</div>
</fieldset>

Controller:
using MvcAjax.Models;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MvcAjax.Controllers
{
public class HomeController : Controller
{
private SqlConnection con;

// GET: AddEmployee
public ActionResult AddEmployee()
{

return View();
}
//Post method to add details
[HttpPost]
public ActionResult AddEmployee(Employee obj)
{
AddDetails(obj);

return View();
}

//To Handle connection related activities
private void connection()
{
string constr = ConfigurationManager.ConnectionStrings["SqlConn"].ToString();
con = new SqlConnection(constr);

}
private void AddDetails(Employee obj)
{
connection();
SqlCommand com = new SqlCommand("AddEmp", con);
com.CommandType = CommandType.StoredProcedure;
com.Parameters.AddWithValue("@Name", obj.Name);
com.Parameters.AddWithValue("@City", obj.City);
com.Parameters.AddWithValue("@Address", obj.Address);
con.Open();
com.ExecuteNonQuery();
con.Close();

}
}

}

Answer

If you're doing a post expecting the results of the POST back, return Json rather than a View

return Json(new {Success = true});

or whatever status you want to return. Returning a View works well if you're returning a web view for a browser.

Keep in mind, if you want to return JSON data with a GET, you'll need to construct your return statement differently

return Json(new {Success = true}, JsonRequestBehavior.AllowGet);
