Не обновляется собственное View при изменении полей класса

Question

Написал собственно View. HexaView наследует класс View. Туда добавлены поля:

var angle_cren: Float = 15f
var angle_tang: Float = 10f
var angle_risk: Float = 225f

Также есть две кнопки. Также в MainActivity написаны обработчики нажатий на кнопки(onClickTakeOff, onClickLanding), которые меняют поля angle_cren, angle_tang, angle_risk. Поиск HexaView происходит по id. Проблема заключается в том, что при нажатии на кнопку, значения этих полей меняются, но при этом HexaView не перерисовывается на самом экране. В чем может быть проблема? Как обновить HexaView на экране с новыми параметрами? Код: MainActivity.kt:
