TextView внутри панели инструментов null с помощью Butterknife

Я не прошу решения, но хочу знать, почему TextView внутри Панели инструментов возвращается null? Я использую Butterknife внутри фрагмента.

@BindView(R2.id.toolbarTitle)
    TextView toolbarTitle;

Вот мой макет:

<android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar_widget"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="?attr/colorAccent"
                app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
                >

                <LinearLayout
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="center"
                    android:gravity="center">

                    <TextView
                        android:id="@+id/toolbarTitle"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_gravity="center"
                        android:gravity="center"
                        android:textColor="#ffffff"
                        android:textSize="@dimen/text_size18"
                        android:textStyle="bold" />
                </LinearLayout>
            </android.support.v7.widget.Toolbar>
        </android.support.design.widget.AppBarLayout>

Вот мой лог-кот:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setText(java.lang.CharSequence)' on a null object reference

Хорошо, вот код по запросу:

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.fragment_nav_bookmark_trend_my_quote, container, false);
        toolbarTitle.setText(getString(R.string.bookmarks));
        accessToken = AppSharedPreferences.getsharedprefInstance(getContext()).getStringValue(AppSharedPreferences.KEY_USER_TOKEN);
        mUnbinder = ButterKnife.bind(this, view);
        mLinearLayout = new LinearLayoutManager(getActivity());
        mRecyclerView.setLayoutManager(mLinearLayout);


        DrawerLayout drawer = ((EpicSwiperActivity) getActivity()).drawerLayout;
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                getActivity(), drawer, mToolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.addDrawerListener(toggle);
        toggle.syncState();

        addRecyclerViewScrollState(mRecyclerView);
        return view;
}
