Using the parameter watch to observe the array triggers the callback only when fully replacing the array. If for your callback is required to trigger upon an update as well - indicate the parameter deep:

watch: {
    listElements: {
        handler(currentValue, previousValue) 
            console.log('array is changed');
        deep: true,

You can find more details in the migration guide.
