How to update timer component foreach value to each product using json api ?

**

I am making e-commerce countdown timer sale component. I made separate timer component and passing date and time for the end sale to child component using a @input decorator. this component working fine with one value. when I am using multiple values with JSON API using *ngFor=“let product of cat.products”. Then it’s not working for each product.

**

Timer component

use:

<ion-slide *ngFor="let product of cat.products">
<timerc [dt]="product.timeend"></timerc>
<ion-slide>

Json API
