thanks!!

from documentation, should use ngmodel this:

<ion-item>     <ion-label>pepperoni</ion-label>     <ion-checkbox [(ngmodel)]="pepperoni"></ion-checkbox>     <button (click)="updatedatabaseclicked(errors)">clickonme</button>   </ion-item>

then in ts file:

updatedatabaseclicked(errors){    writeintodatabase(this.pepperoni); }
