Change event on ion-select multiple OR two models in one select?

I have the following code:

<ion-select [(ngModel)]="newFoo.fields" multiple>
    <ion-option *ngFor="let field of fieldStorage" [value]="">{{ }} - {{ field.category_name }}</ion-option>

Where newFoo.fields is an array that’s storing the from fieldStorage, that’s working fine. But I need another array to store all the field.category_names from selected options. I tried adding:


To the select, but that doesn’t seem to do a thing.

if you are using ionic beta 8 or above then the name of event is (ionChange)
or If fieldStorage is not a big array, Once all the selection is done you can try and find it from the array

Using (ionChange) now, doesn’t seem to be working.

Same issue. (ionChange) is not working with ion-select multiple… Any solution?
