Doesn't do rowdeleted event

Hi all:
I have a gridview whose datasource is a arraylist and whose first column is
<asp:CommandField HeaderText="Edición" ShowEditButton="true" EditText="Editar" ShowCancelButton="true" CancelText="Cancelar" ShowDeleteButton="true" DeleteText="Borrar" /> When I click borrar it goes to the rowdeleting event but not to the rowdeleted event. I on't know why
Thanks for any help
