Can't bind to 'NgModel' since it isn't a known property of 'ion-input'

if you are using [(ngModel)] and still getting this error, don't forget to import FormsModule in the current module

You're using:

[(NgModel)]="item.cambio"

when you should be using:

[(ngModel)]="item.cambio"

Change your template code like this:

<ion-item>
  <ion-label>Cambio</ion-label>
  <ion-input type="text" [(ngModel)]="item.cambio" placeholder="e.g:"></ion-input>
</ion-item>
