Values not being posted from Partial View MVC4 - asp.net-mvc

Question

For some reason my partial view is always returning null values to the controller. I've tried implementing this in several different ways (including editor templates) but here's my latest.
Basically I'm rendering a view with a jquery ui datepicker. When the user picks a date I then render my partial view. The partial view is being rendered correctly but when I submit the partial view it's returning a null object to the controller
View Model:
public class Attendance
{
public int RecordId { get; set; }
public int GroupId { get; set; }
public int MemberId { get; set; }
public string MemberName { get; set; }
public System.DateTime Date { get; set; }
public bool Present { get; set; }
}
Parent View:
#{
ViewBag.Title = "Take Attendance";
}
<h2>Take Attendance</h2>
#Html.Hidden("GroupId", (int)ViewBag.GroupId)
<div>
#Html.Label("Select A Date")
#Html.JQueryUI().Datepicker("attendanceDate",ViewBag.AttendanceDate)
.OnSelect("attendanceDate.onSelect")
</div>
<div id="attendanceRecords">
</div>
#section scripts
{
<script src="#Url.Content("../../Scripts/Views/TakeAttendance.js")" type="text/javascript"></script>
}
Partial View:
#model IEnumerable<AT.Manager.Models.Attendance>
#using (Html.BeginForm("TakeAttendance", "Groups")) {
#Html.ValidationSummary(true)
<table>
<tr>
<th>Name</th>
<th>Present?</th>
</tr>
#for (int i = 0; i < Model.Count(); i++ )
{
<tr>
<td>#Html.DisplayFor(model => Model.ElementAt(i).MemberName)</td>
<td>#Html.EditorFor(model => Model.ElementAt(i).Present)</td>
<td>#Html.HiddenFor(model => Model.ElementAt(i).GroupId)</td>
<td>#Html.HiddenFor(model => Model.ElementAt(i).MemberId)</td>
<td>#Html.HiddenFor(model => Model.ElementAt(i).RecordId)</td>
</tr>
}
</table>
<p>
<input type="submit" value="Create" />
</p>
}
Controller Action:
public ActionResult TakeAttendance(IEnumerable<Attendance> records)
{
if (ModelState.IsValid)
{
var newRecords = records.Select(x => new da.Attendance() { Id = x.RecordId, GroupId = x.GroupId, MemberId = x.MemberId, Date = x.Date });
AttendanceRepository attendanceRepo = new AttendanceRepository();
newRecords.Each(x => attendanceRepo.InsertOrUpdate(x));
return RedirectToAction("Index");
}
else
{
return View();
}
}
Any suggestions would be much appreciated.

You could try passing IList<Attendance> records to the view and then manipulate it like this:
for (int i = 0; i < Model.Count(); i++ )
{
<tr>
<td>#Html.DisplayFor(model => Model[i].MemberName)</td>
<td>#Html.CheckBoxFor(model => Model[i].Present)</td>
// ...
</tr>
}
Be sure to change #model IEnumerable<AT.Manager.Models.Attendance> to reflect the change of collection to IList.
