MVC Enum list bind in dropdown using angular JS

I have an MVC Enum List that I want to bind in a dropdown using angular method. How could it possible?

public enum DefultBookType : byte
{
  Not Direct= 0,
  Individual = 1
}

public ActionResult Application(){
  ViewBag.BT = Enum.GetNames(typeof(DefultBookType)).ToList();
  return View();
}

@{
 var lstBT=  @ViewBag.BT
}
<select ng-model="Btype" ng-options="ctr as ctr.Name for ctr in lstBT track by ctr.Id">
   <option value="">select</option>
</select>
