I'd like to call a function of v-calendar (next and prev) from another component.
I have tried with refs, it work to call next and prev from the same component of the v-calendar,
but from a grandparent component it doesn't work.
Child component
<template>
<v-calendar
ref="calendar"
...
></calendar>
</template>
Grandparent component
<template>
<v-btn @click="$refs.calendar.next()">
<v-icon>
keyboard_arrow_right
</v-icon>
</v-btn>
</template>
