Ionic 4 - ion-input Two Way Binding

In Ionic 4 how do you do two-way binding. In Ionic 3 I would do the following:

<ion-item color="light"> <ion-input type="string" placeholder="Username" [(ngModel)]="username"></ion-input> </ion-item>

However in Ionic 4 I get the following error:

Can't bind to 'ngModel' since it isn't a known property of 'ion-input'.
    1. If 'ion-input' is an Angular component and it has 'ngModel' input, then verify that it is part of this module.
    2. If 'ion-input' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
    3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("d>
              <ion-item color="light">
                  <ion-input type="string" placeholder="Username" [ERROR ->][(ngModel)]="username"></ion-input>
              </ion-item>
              <ion-item color="light">
    "): ng:///AppModule/LoginPage.html@12:62

How do I get this working in Ionic 4?
