PIServer.FindChangedPIPoints PIServer Refresh

I change a value in PI System Explorer, but PIServer.FindChangedPIPoints always returns null. Do I need to refresh the server object?  The PIServer object looks good. But never changes.


   PIPointChangesCookie cookie = _piPointChangeCookieDict[kvp.Key];
   IList<PIPointChangeInfo> changes = piServer.FindChangedPIPoints(int.MaxValue, cookie, out cookie);
   _piPointChangeCookieDict[kvp.Key] = cookie;

   if (!ReferenceEquals(changes, null))
