error on partial view data are not pasted to the model - asp.net-mvc-5

Question

Good day. I really do not know which part will I fix.
This is the view model
public class EmployeeViewModel
{
public int ID { get; set; }
public string LastName { get; set; }
public string FirstName { get; set; }
public virtual ICollection<FacultySchedViewModel> FacultyScheduleViewModels { get; set; }
}
public class FacultySchedViewModel
{
public int ID { get; set; }
public int EmployeeID { get; set; }
public string Schedule { get; set; }
public string Room { get; set; }
}
the main view- in here i will just hide or show it because it is optional.
#Html.Partial("_Create", new LeavesAndTrainings.ViewModels.FacultySchedViewModel())
and in the main view the javascript to dynamically create a textboxes in the partial view
<script>
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for (var i = 0; i < colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[0].cells[i].innerHTML;
switch (newcell.childNodes[0].type) {
case "text":
newcell.childNodes[0].value = "";
break;
case "checkbox":
newcell.childNodes[0].checked = false;
break;
case "select":
newcell.childNodes[0].selectedIndex = 0;
clear_attrib();
break;
}
}
}
function deleteRow(tableID) {
try {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
for (var i = 0; i < rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0];
if (null != chkbox && true == chkbox.checked) {
if (rowCount <= 1) {
alert("Cannot delete all the rows.");
break;
}
table.deleteRow(i);
rowCount--;
i--;
}
}
} catch (e) {
alert(e);
}
}
this is the partial view - used BeginCollectionItem to dynamically create an index on the textboxes
<table class="table" id="AddSchedule">
#using (Html.BeginCollectionItem("FacultySchedViewModel"))
{
<tr>
<td><input type="checkbox" name="chk[]" class="checkbox_style" /></td>
<td>
#Html.HiddenFor(model => model.ID, new { htmlAttributes = new { #class = "form-control" } })
</td>
<td>
#Html.EditorFor(model => model.Schedule, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Schedule, "", new { #class = "text-danger" })
</td>
<td>
#Html.EditorFor(model => model.Room, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Room, "", new { #class = "text-danger" })
</td>
<td>
#Html.EditorFor(model => model.Subject, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Subject, "", new { #class = "text-danger" })
</td>
</tr>
}
</table>
<div class="form-group">
<div class="col-md-12">
<input type="button" name="add" value="Add" class="btn btn-default" onclick="addRow('AddSchedule')">
<input type="button" name="remove" value="Remove" class="btn btn-default" onclick="deleteRow('AddSchedule')">
</div>
</div>
and the controller
public ActionResult Create()
{
EmployeeViewModel employeeViewModel = new EmployeeViewModel();
ICollection<FacultySchedViewModel> schedViewModel = new List<FacultySchedViewModel>();
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(EmployeeViewModel employeeViewModel, ICollection<FacultySchedViewModel> schedViewModel)
{
if (ModelState.IsValid)
{
var emp = db.Employee.Create();
emp.ID = employeeViewModel.ID;
emp.LastName = employeeViewModel.LastName;
emp.FirstName = employeeViewModel.FirstName;
db.Employee.Add(emp);
if (schedViewModel != null)
{
var sched = db.FacultySchedule.Create();
foreach (var aaa in schedViewModel)
{
sched.EmployeeID = employeeViewModel.ID;
sched.Schedule = aaa.Schedule;
sched.Room = aaa.Room;
sched.Subject = aaa.Subject;
}
}
db.SaveChanges();
return RedirectToAction("Index");
}
after running the create, and click the save button, EmployeeViewModel employeeViewModel is valid and not null, but the ICollection<FacultySchedViewModel> schedViewModel is null. I tried to use only EmployeeViewModel employeeViewModel but I do not know how to save it. I save the model in that way because there are default values and values to be extracted from other tables.
