Angular2 - using 3rd parety module's component - angularjs

Question

I created a module which has a directive in it (ObDatePickerModule).
Also I created a project which has ObDatePickerModule in it's dependencies (under dependencies in package.json).
Next I am importing Module A in my project's module:
import {BrowserModule} from '#angular/platform-browser';
import {NgModule} from '#angular/core';
import {FormsModule} from '#angular/forms';
import {ObDatePickerModule} from 'ng2-date-picker';
import {AppComponent} from './app.component';
#NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
FormsModule,
ObDatePickerModule,
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule {
}
Here is the app.component of the project:
import {Component} from '#angular/core';
import {ObDayPickerComponent} from 'ng2-date-picker';
import * as moment from 'moment';
#Component({
selector: 'app-root',
template: '<ob-day-picker [(ngModel)]="date"></ob-day-picker>',
styleUrls: ['./app.component.css'],
entryComponents: [ObDayPickerComponent]
})
export class AppComponent {
date = moment();
}
Here is the error that I am getting:
main.bundle.js:66421 Unhandled Promise rejection: Template parse errors:
'ob-day-picker' is not a known element:
1. If 'ob-day-picker' is an Angular component, then verify that it is part of this module.
2. If 'ob-day-picker' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '#NgModule.schemas' of this component to suppress this message. ("[ERROR ->]<ob-day-picker [(ngModel)]="date"></ob-day-picker>
I checked that the component name is really ob-day-picker.
I have also consoled log both the module and the ObDayPickerComponent imports and it seems that the imports are correct.
What did I miss?
Checkout the module repo:
https://bitbucket.org/vlio20/ng2-date-picker
The project can be found here:

If you want to use ObDayPickerComponent outside of ObDatePickerModule you have to export it like:
#NgModule({
declarations: [
AppComponent,
ObDayPickerComponent,
ObCalendarComponent
],
imports: [
BrowserModule,
FormsModule
],
exports: [ObDayPickerComponent], // this line
bootstrap: [AppComponent]
})
export class ObDatePickerModule {}
