If I set the configuration option "minView" as a variable and the value of this variable changes, view is not updated. <datetimepicker data-ng-model="event.endsAt" data-datetimepicker-config="{ dropdownSelector: '#dropdown_endsAt', minView: minView }" data-before-render="beforeRender($view, $dates, $leftDate, $upDate, $rightDate)" /> If I change the minView before initialization (from minute to day), behaviour doesn't change.
