When the input is being initialized, updateFromElementVal() is called and eventually the update() is called, which triggers the event changeTime.timepicker.
I think changeTime.timepicker should only trigger only when the value is changed after initialization.
confirmed on kartik-v/yii2-grid... causes an infinite page loop for apps which trigger page refresh OnChange of the input. The input change event should not be triggered somehow on init.
did anything ever happen with this?
Are you fixed an error already?
