I am able to archive to get all data sucessfully from following code

public Object Get()
{
     var employeeList = _db.Employees;
     var result = new
     {
         data = employeeList
     };
     return this.Json(result, JsonRequestBehavior.AllowGet);
}

but when i am passing data to extjs model it will give following Error enter image description here

I am able to get my all data from database but Don't know where I am wrong?

The circular reference is caused by the Json serialization.
