Short description of the problem:

I have an project with tabs, but the (click)-event doesn’t work and if I leave the attribute [root] away (not required because I want to show an action sheet), then the app crashes.

What behavior are you expecting?
Click on the tab and see the action sheet appear

<ion-tabs>
  <ion-tab tabTitle="Tab 1" tabIcon="pulse" (click)="presentActionSheet()"></ion-tab>
</ion-tabs>
presentActionSheet() {
        let actionSheet = ActionSheet.create({
            title: 'Modify your album', buttons: [{
                text: 'Destructive', role: 'destructive', handler: () => {
                    console.log('Destructive clicked');
                }
            }, {
                text: 'Archive', handler: () => {
                    console.log('Archive clicked');
                }
            }, {
                text: 'Cancel', role: 'cancel', handler: () => {
                    console.log('Cancel clicked');
                }
            }]
        });
        this.navController.present(actionSheet);
    }

What Solution are you finding?

<ion-tabs>
  <ion-tab tabTitle="Tab 1" tabIcon="pulse" (ionSelect)="presentActionSheet()"></ion-tab>
</ion-tabs>
