Для отслеживания изменения вводимого значения используется событие "number-changed" (константа
NumberChangedEvent). Основной слушатель события имеет следующий формат:
func(picker NumberPicker, newValue float64)
func(picker NumberPicker, newValue, oldValue float64)
где второй аргумент это новое значение
где второй аргумент это новое значение, третий аргумент - предыдущее значение.
Дополнительные слушатели события могут иметь следующий формат
