how to submit JSON Array to Database Table in ASP.Net MVC4

Here is JSON Code to post that array to GetBulk Method:

$("#button").click(function () {
    var array = [
        {
            StudentRecordId: 1,
            Name: "Amit",
            Marks: 11,
            Grade: "A"
        },
        {
            StudentRecordId: 2,
            Name: "Abhishek",
            Marks: 12,
            Grade: "A"
        },
        {
            StudentRecordId: 3,
            Name: "Vipin",
            Marks: 13,
            Grade: "A"
        }
    ]

    $.ajax({
        type: "Post",
        url: "/Home/GetBulk",
        dataType: "json",
        traditional:true,
        data: JSON.stringify({ data: array }),
        traditional: true,//"feedGraphId=10696",
        success: function (result) {
            alert("j= " + result.studentRecord);                 
        },
        error: function (XMLHttpRequest, textStatus, errorThrown) {
            alert("error" + errorThrown);
        }
    });
});                

Here is method of my controller:

//to recieve array from json and post values to student record table
public JsonResult GetBulk(List<StudentRecord> models)
{
    StudentRecord studentRecords = new StudentRecord();

    foreach(var item in models)
    {
        studentRecords.Name = item.Name;
        studentRecords.Marks = item.Marks;
        studentRecords.Grade = item.Grade;
        db.StudentRecords.Add(studentRecords);
        db.SaveChanges();
    }

    var c = db.StudentRecords.ToList();
    return Json(models, JsonRequestBehavior.AllowGet);
}

Here is my Model:

public class StudentRecord
{
    public long StudentRecordId { get; set; }
    public string Name { get; set; }
    public int Marks { get; set; }
    public string Grade { get; set; }
}

So then how can I submit my values to a table using this json array?
