Addlistener on OnEndReach in code is not working

[Sidar]

I have the following

Code:

dc = GetComponent<DebtCollector>();
       if (dc != null)
       {


           if (sc != null && !sc.Spline.Closed)
           {

               sc.OnEndReached.AddListener(e => {
                   if (dc != null)
                       dc.Collect();
               });
               sc.OnEndReached.CheckForListeners();


           }
       }

But the function is never called.
Any idea what is causing this?

I also tried by passing a member function but non is working.
