Modal Component guide and example throw exceptions

Bug description:

The Modal as a component plnkr linked from the guide doesn’t work when you click the button. It throws the exception:

Error in src/modal-component.html:3:47 caused by: No component factory found for NgbdModalContent

I’m actually getting the same error in my own code, not experienced enough with Angular2 yet to be able to figure out how to fix it.

Plnkr:

https://ng-bootstrap.github.io/app/components/modal/demos/component/plnkr.html

Version of Angular, ng-bootstrap, and Bootstrap:

Angular: 2.0.2

ng-bootstrap: 1.0.0-alpha.8

Bootstrap: 4.0.0-alpha.4

in the lazy module. we need reimport the NgbModule,just like root module.

@NgModule({
    imports: [
        CommonModule,
        FormsModule,
        NgbModule.forRoot(),
        routing
    ],
    providers: [I18nService],
    declarations: [I18nComponent,
        ListComponent, StartComponent, ProjectComponent, ModuleComponent,
        CustomModalContent],
    entryComponents:[CustomModalContent]
})
export class I18nModule {
}

then it is working but i don`t known why!!!

@Syes-K this shouldn’t be needed and in child components you should just add NgbModule instead of NgbModule.forRoot(). If this doesn’t work could you please open a separate issue for lazy-loaded modules? Just please add a minimal reproduce scenario in a plunker, see: https://github.com/ng-bootstrap/ng-bootstrap#you-think-youve-found-a-bug)
