Nativescript radListView do not show Item

Question

Overview

Nativescript radListView does not show bind item from component on both ios and android os.
Action bar and usual ListView shows data but radlistview do not. Console shows no error. But I saw RadListView from next repository can work -> https://github.com/telerik/nativescript-ui-samples-angular

Environment

My development environment is below.

os: macOS sierra 10.12.6
node : v6.12.0
npm : 3.10.10
nativescript and others can be seen after, at package.json

Consideration

I seems this problem is about these...
but I can not refine.

angular directive
initializing an observable array

Code

I implemented RadListView on angular like below just after 'tns create ui-test --ng'.

Component

export class ItemsComponent implements OnInit {
    private _dataItems: ObservableArray<Item>;

    constructor() {
    }

    get dataItems(): ObservableArray<Item> {
        return this._dataItems;
    }

    ngOnInit() {
        this._dataItems = new ObservableArray([
            { id: 1, name: "Ter Stegen", role: "Goalkeeper" },
            { id: 3, name: "Piqué", role: "Defender" },
            { id: 4, name: "I. Rakitic", role: "Midfielder" }
        ]);
    }
}

html

<ActionBar title="My App" class="action-bar">
</ActionBar>

<GridLayout>
    <RadListView [items]="dataItems">
        <ng-template let-item="item">
            <StackLayout>
                <Label class="nameLabel" text="text"></Label>
                <Label class="nameLabel" [text]="item.name"></Label>
                <Label class="descriptionLabel" [text]="item.role"></Label>
            </StackLayout>
        </ng-template>
    </RadListView>
</GridLayout>

I did get your code and put in the home.component After the tns create uitest --ng then tns plugin add nativescript-ui-listview tns platform remove android tns platform add android tns build android tns run android

It works if you don't forget to import this module in the home.module.ts : NativeScriptUIListViewModule

import { NgModule, NO_ERRORS_SCHEMA } from "@angular/core";
import { NativeScriptCommonModule } from "nativescript-angular/common";
import { NativeScriptUIListViewModule } from "nativescript-ui-listview/angular";

import { HomeRoutingModule } from "./home-routing.module";
import { HomeComponent } from "./home.component";

@NgModule({
  imports: [
    NativeScriptCommonModule,
    HomeRoutingModule,
    NativeScriptUIListViewModule
],
declarations: [
    HomeComponent
],
schemas: [
    NO_ERRORS_SCHEMA
]
})
export class HomeModule { }

with this item.model.ts

export class Item {
  id: number;
  name:string;
  role: string;
}

Important

In one another project, it didn't work until I add theses lines in the app.module.ts

import { NativeScriptUIListViewModule } from "nativescript-ui-listview/angular/listview-directives";

@NgModule({
imports: [
    ...
    NativeScriptUIListViewModule
