title: sharepoint online remote event receiver does not working
body: <p>Hello i recently started to developing sharepoint 2013 .
  I deply my solution to office365 online account and to my solution i attached remote event receiver.
  This event receiver should listen to particular events(in this case adding to a custom list)
  and then perform action.
  Problem is that this action is never performed. It seems that event receiver is not event firing when event occurs.
  Any ideas ? anyone had similar problem?
  best regards</p>
