how to update the modal by an action on a button its content will change according to the action, I need your help I am a beginner and I am blocked this one class is The viewModal

    using System.Collections.Generic;  namespace personnelAUTHENTIFICATION.Models {     public class EditViewModel      {                         public IEnumerable<PersonnelModel> personnels { get; set; }         public IEnumerable<DocumentModel> documents { get; set; }     } }
