Access Slick modal from component

[mina-thomas]

I want to access slick modal from component, I tried it using ViewChild but it didn't work.
here is my code:

<ngx-slick class="carousel col-md-12" #slickModal="slick-modal" [config]="slideConfig" (afterChange)="afterChange($event)">
<div ngxSlickItem *ngFor="let slide of slides; let i = index" class="slide">

@ViewChild('slickModal') public slickModal;

but i always have undefined in slickModal when this.slickModal.slickGoTo(2);

any help?
Thanks
