Probably due to these errors printed to the console:
qrc:/qml/TimerForm.qml:167: ReferenceError: timer is not defined
qrc:/qml/TimerForm.qml:167: ReferenceError: timer is not defined
qrc:/qml/TimerForm.qml:167: ReferenceError: timer is not defined
qrc:/qml/TimerForm.qml:0: ReferenceError: timer is not defined
