checkbox not detect change from yes to no when check action ApprovalIn

I work on asp.net MVC app . I face issue checkbox value not detected changing value from true to false or reverse .

meaning if I change checkbox Value from Yes to No OR No to Yes nothing detected according to speakstuff property model .

Exactly I need when checkbox check for yes then true and if check box for No will be false .

html script represent yes or No check box

            

                

                    @Html.Label("Did You Meet/Speak to Staff", htmlAttributes: new { @class = "control-label col-md-5" })
                    

                        
                        Yes
                          
                        
                        No
                    
                

And below is jQuery to allow only selection with yes or no

model that represent property SpeakStuff

 public class ResignationRequester
    {
        [Display(Name = "Employee No : ")]
        [Required]
        public int EmpID { get; set; }
        [Display(Name = "Request No")]
        public int RequestNo { get; set; }
        public bool SpeakStuff { get; set; }

    }

and When click approve button and check speakstuff property it still not changed

using (Html.BeginForm("ApprovalIndex", "Resignation", new { id = Model.RequestNo }, FormMethod.Post, htmlAttributes: new { @style = "display:inline;" }))
        {
            

             Approve 
            
        }

when debug model ResignationRequester speakstuff property it still true on all cases and if I change check box selection it still without change .

//post action method type
      
        public async Task ApprovalIndex(ResignationRequester REQ)
        {
        }

So How to solve this issue ?
