How do I add a title to my menu group

I use this code for my project, take a look:

<item
    android:title="Search Option"
    android:id="@+id/menu_search_option"
    android:showAsAction="ifRoom|withText">
    <menu>
        <group>
            <item
                android:id="@+id/menuSearchFilmEpisode"
                android:title="Episode"/>
            <item
                android:id="@+id/menuSearchActor"
                android:title="Actor"/>
            <item
                android:id="@+id/menuSearchDirector"
                android:title="Director"/>
        </group>
    </menu>
</item>

And the result is that i have a group with text as icon on my action bar. Hope it helps.
