How to watch for ngSwitchCase in Ionic 2 / Angular 2?

Question

I have a simple ngSwitchCase scenario

I want to watch for and get notified of ngSwitchCase in the controller, Basically when i switch between tabs.

Any ideas?

```ionChange``` expression to evaluate when a segment button has been changed — Alex Filatov, Sep 08 '16 at 16:20

Looking at the docs I see there is an output event called ionChange. You could hook into that:

<ion-segment [(ngModel)]="selectedTab" (ionChange)="selectedTabChanged($event)">
    ...
<ion-segment>

And in your component you then have your method:

selectedTabChanged($event): void {
    // do something here
}

what about angular 2? – Alex Filatov Sep 08 '16 at 16:22
`ionChange` works, i guess it can be used in all other instances – Patrioticcow Sep 08 '16 at 16:31
@rinukkusu try `(ngModelChange)="onChange($event)"` or `(change)="onChange(item.value)"` – Patrioticcow Sep 08 '16 at 16:35
