i tried using @viewchild, @viewchildren getting undefined in aftercontentinit method.

 @viewchild(validationalertscomponent)   private validationalerts: validationalertscomponent;

component class

@component({   selector: 'provision-modal',   templateurl: 'provision.modal.html',   encapsulation: viewencapsulation.none,   styles : [ '.namelookup .modal-content {  width: 600px;}']  }) export class provisionmodal implements aftercontentinit {   @viewchild('content')  contenttemplate: templateref<any>;     @viewchild(validationalertscomponent)   private validationalerts: validationalertscomponent;       ngaftercontentinit() {      console.log('ng after content init '+ this.validationalerts);   }
