Striving to incorporate lazy loading in Angular 2, I have successfully implemented lazy loading by following this helpful guide. Within my application, I have two components - home1 and home2. Home1 showcases the top news section, while home2 is dedicated to listing other news articles. Initially, only home1 is displayed to the user. Upon scrolling, I aim to load home2 within home1 (similar to calling a partial view in MVC).
I attempted to call home2 within home1 using
<app-home2-list></app-home2-list>
, but encountered an error in the process.

I am unsure of the correct method to call the home2 HTML within the home1 HTML. Are there alternative approaches available to achieve this integration?
Within my app.module.ts:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { MenuComponent } from './menu.component';
import { HomeComponent } from './home/home.component';
import { Const_Routing } from './app.routing';
import { HttpModule } from '@angular/http';
import { Home2ListComponent } from './home2/home2-list/home2-list.component';
import { Home1ListComponent } from './home1/home1-list/home1-list.component';
@NgModule({
declarations: [
AppComponent,
MenuComponent,
HomeComponent,
Home1ListComponent,
Home2ListComponent
],
imports: [
BrowserModule,
Const_Routing,
HttpModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
