Only check the checkbox if the value of ngModel is true

Question

When my checkbox is clicked the value of my ngModel produto.checked is set to true , but in a moment this value is changed to false without a click in the checkbox. How can i make my checkbox only check/uncheck according by my ngModel ?

I try something like:

<tr *ngFor="let produto of sortedDataProduto; let i = index">
   <input [checked]="produto.checked" [(ngModel)]="produto.checked" name="checkedproduto{{i}}" type="checkbox">
</tr>

Answer 1

Delete from your code [checked]="produto.checked ". [(ngModel)]="produto.checked" is enough to show initial value.

Answer 2

You are binding your produto.checked twice use either [checked] or [(ngModel)]
if you still have problem please be more specific.
