[Vuejs]-VueJs: Inertia event listener not working

I’m having the same problem. Unfortunately, it’s not working as documented. 🙁

Since, the method is returning a promise, you can workaround like this:

this.sending = true
this.$inertia.post('/email/store', data)
  .then(() => this.sending = false);

EDIT:
Events have been introduced with version 0.3. Which version are you using?
