Дата списка страниц mvc теряет значение на второй странице

У меня есть индексная страница с различными параметрами фильтрации, все они включены в PagedList. Все работает нормально, кроме дат.

Когда я впервые фильтрую по дате, они работают нормально, однако, когда я нажимаю номер страницы внизу, критерии поиска моей даты исчезают.

Я вижу, что могу передать поисковый запрос в выгружаемом списке, и я вижу, что эта дата попадает в мой контроллер, и происходит фильтрация, но ViewBag.filterStartDate и ViewBag.filterEndDate по какой-то причине просто не привязываются к моим текстовым полям.
