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.
