Calling function to save and redirect route: Laravel 5.2

I have following functions in Controller.

public function UpdateCountry(\App\Http\Requests\CountryRequest $request) {
    $this->SaveChanges($request);
}

private function SaveChanges($request) {
    if($request['CountryID'] == 0) {
        $Country = new \App\Models\CountryModel();
    }
    else {
        $Country = \App\Models\CountryModel
                  ::where('CountryID', $request['CountryID'])->first();
    }

    $Country->Country = $request['Country'];
    $Country->CountryCode = $request['CountryCode'];
    $Country->save();
    return redirect()->route('AllCountries');
}

public function AllCountries() {
    $Countries = \App\Models\CountryModel::all();
    return view('Country.List', array('Countries' => $Countries));
}

Issue is in below line: When I call function SaveChanges, I am not able to see List of countries page and when I write the code directly in UpdateCountry function, it redirect route successfully.

return redirect()->route('AllCountries');

Anybody faced this issue before ?
