Property 'onDidDismiss' does not exist on type Modal

Hi there,

I’m wondering how can I get rid of this typescript error message? Modal extends ViewController, does this mean typescript couldn’t find the inherited property?

Property 'onDidDismiss' does not exist on type Modal

Thanks.

My system information:

Cordova CLI: 6.0.0
Ionic Framework Version: 2.0.0-beta.11
Ionic CLI Version: 2.0.0-beta.25
Ionic App Lib Version: 2.0.0-beta.15
ios-deploy version: 1.8.5
ios-sim version: 5.0.6
OS: Mac OS X El Capitan
Node Version: v4.3.0
Xcode version: Xcode 7.3.1 Build version 7D1014

I might have just answered my own question:

import {ViewController} from 'ionic-angular'
...
(<ViewController>accountModal).onDidDismiss(data => {

})

Hope this helps others.
