I have assigned a custom handler to $scope.uiConfig.calendar.events parameter. When calendar is loaded or current month is changed via left or right button the handler called twice.
While searching through demo file I saw that adding handler to $scope.eventSources instead of registering it to calendar.events make it work correctly.
