Restore button text in fragments

I have fragment witch contains button. Here is layout:

    <LinearLayout
    android:id="@+id/filters_container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <Button
        android:id="@+id/button_open_filters"
        style="@style/no_elevation"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.76"
        android:background="@drawable/selector_button_search_menu"
        android:clickable="true"
        android:gravity="start|center_vertical"
        android:paddingBottom="@dimen/tv_padding_top_search_menu"
        android:paddingLeft="@dimen/et_padding_left"
        android:paddingRight="@dimen/et_padding_left"
        android:paddingTop="@dimen/tv_padding_top_search_menu"
        android:text="@string/button_searchname_all"
        android:textColor="@color/dark_white_pressed_selector" />

    <ImageButton
        android:id="@+id/button_filter"
        style="@style/no_elevation"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="0.12"
        android:background="@drawable/selector_button_search_menu"
        android:paddingBottom="@dimen/tv_padding_top_search_menu"
        android:paddingTop="@dimen/tv_padding_top_search_menu"
        android:src="@drawable/bg_button_filters" />

    <ImageButton
        android:id="@+id/button_clear_filter"
        style="@style/no_elevation"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="0.12"
        android:background="@drawable/selector_button_search_menu"
        android:paddingBottom="@dimen/tv_padding_top_search_menu"
        android:paddingTop="@dimen/tv_padding_top_search_menu"
        android:src="@drawable/selector_button_reset_filters"
        android:visibility="gone" />

</LinearLayout>

So button_open_filters has dynamically change text. In fragment i have:

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
      View view = inflater.inflate(R.layout.fragment_search, container, false);
    if(savedInstanceState != null) {
      //some code
    } else {
     //restore prevous state
}
return view;

}

but in debug mode i see that savedInstanceState has no state for button: android:view_state={2131624078=android.view.AbsSavedState$1@4191c450}

So my question what I'm doing wrong ? State for button is not saved by android, for example i too have Textview that state was saved and propertly restored by android.
