Facebook Login Button has no action

I'm testing the Facebook Login API, however clicking the Signing in with Facebook button will not happen, only the bar where the time is black for a moment and then comes back with the color of the application defined in styles.xml file. It does not even occur in any of the three events of the attribute facebookCallBack , onSuccess() , onError() and onCancel() .

MainActivity.class :

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
}

MainActivityFragment.class :

public class MainActivityFragment extends Fragment {

    TextView description;
    CallbackManager callbackManager;
    FacebookCallback<LoginResult> facebookCallback = new FacebookCallback<LoginResult>() {

        @Override
        public void onSuccess(LoginResult loginResult) {
            AccessToken accessToken = loginResult.getAccessToken();
            Profile profile = Profile.getCurrentProfile();
            if (profile != null){
                description.setText("Bem-vindo, " + profile.getFirstName());
            }
        }

        @Override
        public void onCancel() {
            Toast.makeText(getContext().getApplicationContext(), "Cancelado!", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onError(FacebookException error) {
            Toast.makeText(getContext().getApplicationContext(), "Erro!", Toast.LENGTH_LONG).show();
        }
    };

    public MainActivityFragment() {
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_main, container, false);
        description = (TextView) view.findViewById(R.id.description);

        callbackManager = CallbackManager.Factory.create();

        LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
        loginButton.setReadPermissions("email");
        loginButton.setFragment(this);

        loginButton.registerCallback(callbackManager, facebookCallback);

        return inflater.inflate(R.layout.fragment_main, container, false);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }
}
