events don't work properly

[ShmidtAlex]

No one of commonly used events and no one of described events from manual has connection to parent's component functions.
<datepicker
v-model="event.date"
placeholder="Select a date"
:input-class="{ error: $v.event.date.$error }"
@opened="sendMessage"
@click="sendMessage"
@input="sendMessage"
@blur="sendMessage"
:id="1"
:required="true"
/>
function 'sendMessage' doesn't evoked at all

For some reason it appears there's a release that isn't listed on the releases page that is messing all that up (1.6.2)
If you roll back to 1.5.1 they are all there. I know theres is years after but thought it might be useful for someone
