temporary can be fixed by adding :model-value="${model.hour}:${model.minute}"

also try to change the time in right(fixed) picker. left picker does not react.

The intended use of the v-model looks like v-model="model" and const model = ref('3:30'). You could use a computed to save it as an object the way you're trying here...
