    I'm developing aspnetzero application with angular but when I'm assigning value of categories property in p-dataTable I'm getting this error in browser console:

    Can't bind to 'value' since it isn't a known property of 'p-dataTable'

    I have three files. First file categories.component.ts

    import { Component, Injector, OnInit } from '@angular/core';
    import { AppComponentBase } from '@shared/common/app-component-base';
    import { appModuleAnimation } from '@shared/animations/routerTransition';


    import { Http, Response, Headers, RequestOptions } from "@angular/http";
    import { AppSessionService } from '@shared/common/session/app-session.service';
    import { Category } from './category';
    import { DataTableModule, SharedModule, DataTable } from 'primeng/primeng';


    @Component({
    templateUrl: './categories.component.html',
    animations: [appModuleAnimation()]
    })
    export class CategoriesComponent extends AppComponentBase implements OnInit {

    categories: Category[];

    constructor(
    injector: Injector,
    private http: Http,
    private appSessionService: AppSessionService
    ) {
    super(injector);
    }

    ngOnInit(): void {
    this.getCategories();
    }

    getCategories(): void {

    let headers = new Headers({ 'Content-Type': 'application/json' })
    headers.append('tenantId', this.appSessionService.tenant ? this.appSessionService.tenant.id.toString() : '-1');
    let options = new RequestOptions({ headers: headers });
    this.http.get('/api/categories', options).subscribe(values => {
    this.categories = values.json();
    });
    }
    }


    Second categories.component.html

    <div [@routerTransition]>
    <div class="row margin-bottom-5">
    <div class="col-xs-12">
    <div class="page-head">
    <div class="page-title">
    <h1>
    <span>{{l("Categories")}}</span>
    </h1>
    </div>
    </div>
    </div>
    </div>

    <div class="portlet light margin-bottom-0">
    <div class="portlet-body">
    <p-dataTable [value]="categories">
    <p-column field="category.Name" header="Category"></p- column>
    </p-dataTable>
    </div>
    </div>
    </div>


    and Category class

    export class Category {
    constructor(
    public id: number,
    public name: string) { }
    }


    This is app.module.ts
