Here in the docs it says you can two-way bind both selectedDate and currentView by using v-model's attribute.

Obviously that's not working..
Two-way binding for selectedDate works this way (verified):
<ejs-schedule v-model:selectedDate="selectedDate"></ejs-schedule>
As for currentView I haven't verified how it's implemented, maybe that works with the default v-model.
