EF C# Razor 응용 프로그램을 빌드하려고합니다. 드롭 다운 상자 [listbox]의 선택 항목에 getRecruiter (해당 값 포함)라는 경로를 호출하고 recruitername 텍스트 상자를 신입 사원으로 변경하는 데 계속 실패하고 있습니다.드롭 다운에서 텍스트 상자를 채우는 C# Razor
오류 : Uncaught ReferenceError : RecruiterName이 정의되지 않았습니다. 누구든지 나를 도울 수 있으면 크게 감사하겠습니다. Razor 및 C#을 사용하는 방법을 배우려고 노력 중이며 온라인에서 찾을 수있는 모든 것을 시도했습니다.
Notes Model:

using System.Web;
namespace JOM.Models
{
public class NotesModel
{
[Key]
public int NotesID { get; set; }
public int JobID { get; set; }
public string Recruiter { get; set; }
public string NoteTitle { get; set; }
public string NoteData { get; set; }
public DateTime ActiveDate { get; set; }
}
public class JobWithRecruiter
{
public int JobID { get; set; }
public string RecruiterName { get; set; }
}
}
