Ionic 3: ng-change doesn't work

Question

I have a input field where a user can input his address and get auto-suggestions:

 Adresse:
             


        

Answer 1

ng-model and ng-change were used in Angular 1.

With Ionic >= 2, you can use ngModel and ionChange.

The parentheses signify that data binding is from the template to the component, the square brackets, component to the template. When both are present, it is a two way data binding.

For more info on template syntax, look at the Angular docs.
