title: Fullcalendar Not Working Other Methods Vue JS
body: <p>I'm working with the Fullcalendar Vue. I want to click on the relevant event and take action. I can catch it with Watch or run a Function, but I can't go outside. What's the problem?</p>
  <pre><code>eventClick: function(info){
     console.log(info.event.id); // Console Log 25
     this.calendarEvent = info.event.id; // Not Write
     this.changeEventData(info.event.id); // Not Working (this.changeEventData is not a function)
  }
  </code></pre>
