Could you tell me what's wrong with the following Subscription example?

Question

The following Subscription doesn't work at all, When Click a refresh Button. There is no printed Logs indicate that is there any API called.

-Notes: All Dependencies done using dagger2, and Retrofit instance created like this:

@AppScope
    @Provides
    public Retrofit retrofit(OkHttpClient okHttpClient) {
        return new Retrofit.Builder()
                .client(okHttpClient)
                .baseUrl("https://~~~~~~~~~~")
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .build();
    }

• Dagger compiled successfully.

[-]In the Presenter..

private final CompositeSubscription compositeSubscription = new CompositeSubscription();
...
//inside onCreate{}
compositeSubscription.add(observeRefresh());
//inside onDestroy{}
compositeSubscription.clear();

// *Here is the part I think that the problem in.

private Subscription observeRefresh() {
        return view.observeBtnRefresh()
                .doOnNext(__ -> view.showLoading())
                .observeOn(Schedulers.io())
                .switchMap(__ -> model.getFoodsResponse())// [-] In model below...
                .observeOn(AndroidSchedulers.mainThread())
//                .doOnNext(model::saveFoodsState)
                .doOnEach(__ -> view.hideLoading())
                .retry()
                .subscribe();
    }

[-] In the view ...

@BindView(R.id.btnRefresh)
    ImageButton btnRefresh;// ButterKnife.bind(this); is Done.
..
public Observable<Void> observeBtnRefresh() {
        return RxView.clicks(btnRefresh);
    }

[-] In the model

@Inject
    FoodsNetwork foodsNetwork;

    public Observable<Response<ResponseBody>> getFoodsResponse() {
        return foodsNetwork.getFoodsResponse();
    }

[-] foodsNetwork ...

public interface FoodsNetwork {

    @GET()
    Observable<Response<ResponseBody>> getFoodsResponse();

}

Thanks for reading any way!

I found what's wrong, and I decided to keep this question because could make other developers to take care of little things. There was a small thing missed in the API method(path and some @Query) and this was make it not working

@GET(".")
Observable<Response<ResponseBody>> getFoodsResponse(@Query String query);
