Ion-checkbox not checked dose not work

Hi all ! Can anyone help please ! Why ion-checkbox with parametr checked=“false” dose not work and we can see checked checkbox ?

<ion-item text-center class="">
        <ion-label class="" text-center></ion-label>
        <ion-checkbox checked="false" text-center [(ngModel)]="down"></ion-checkbox>

It’s not clear what do you want? You can’t see checkbox at all or checkbox is not checked?

  1. checked=“false” set checkbox to unchecked state
  2. Prefer set start value in your component
public down: boolean = false;

snikh, thanks for answer.

But setting it false doesn’t show up on the view
