Не работает динамическое добавление Cron events

Здравствуйте.
Пишу плагин Вордпресс, который добавляет пользовательские папки в uploads/ , также он должен чистить выбранную папку по расписанию. Написал кой-какой код. Привожу обработчик POST запроса. Всё работает, кроме главного — wp_schedule_event() .
Cron работает. записи опубликованные задним числом — публикуются. На странице плагина без пробем получаю список интервалов и задач (только моих там нет). Думаю дело в области видимости, но пробовал регистрируемую функцию очистки подключать в класс плагина — всё равно не работает.
