When I Selecting an event not fired!

[jujogi]

What is the correct way to obtain the information about any event?

<full-calendar :events="events" @event-selected="selectedEvent"/>

<script>
import moment from 'moment'
export default {

  name: 'calendar',
  data () {
    return {
    events: [
            {
            title: 'Peter John M. Doe',
            allDay: false,
            start: moment().hours(6).minutes(0)
            },
    ]
      }
  },
    methods: {
            selectedEvent(calEvent) {
        console.log(calEvent)
        }
    }
}

</script>

And my package.json:

  "dependencies": {
    "date-fns": "^1.30.1",
    "vue": "^2.5.11",
    "vue-full-calendar": "^2.7.0",
    "vue-fullcalendar": "^1.0.9",
    "vuejs-datepicker": "^1.5.4"
  }

I can not display the event information when I click on it. Thanks for help!
