Ionic ion-checkbox [(ngModel)]="! item.open" it does not work

Question

I need to check the items "Not open" in an ion-checkbox, but the item I get from a server is item.open. When I click on the ion-checkbox it doesn't work correctly.

Does anyone have a solution?

ion-checkbox [(ngModel)]="!item.open"

Answer 1

You can use ionChange method so you will be able to keep track of the value.
