Use ngModel like

TS:

  radio: string = 'option1';

  change() {
    if (this.radio == "option2"){
      console.log("heeeey i'm working");
    } else {
      console.log("heeeeeey i'm still working");
    }
  }

HTML:

<ion-select (ionChange)="change()" [(ngModel)]="radio">

<ion-option value="option1">Option 1</ion-option>

<ion-option value="option2">Option 2</ion-option>

<ion-option value="option3">Option 3</ion-option>

<ion-option value="option4">Option 4</ion-option>

</ion-select>
