Custom Action View can't be clicked

I am trying to add a custom ActionView to my ActionBar.

I am trying to add the common refresh button. (ImageButton, ProgressBar inside a FrameLayout) but if I use an ActionView onOptionsItemSelected() is never called.

Here's the code:

In my Activity:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.messages_actionbar, menu);
mRefreshView = (RefreshView) menu.findItem(R.id.messages_refresh).getActionView();

return super.onCreateOptionsMenu(menu);
}

messages_actionbar's src:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@+id/messages_refresh"
        android:title="title"
        android:icon="@drawable/icon"
        android:showAsAction="always"
        android:actionViewClass="com.blabla.RefreshView"/>
</menu>

RefreshView's code:

public class RefreshView extends FrameLayout {

    private ImageView mButton;
    private ProgressBar mProgressBar;
    private boolean mLoading;

    public RefreshView(Context context) {
        super(context, null);
        initView(context);
    }

    public RefreshView(Context context, AttributeSet attrs) {
        super(context, attrs, 0);
        initView(context);
    }

    public RefreshView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        initView(context);
    }

    private void initView(Context context) {
        LayoutInflater inflator = LayoutInflater.from(context);
        View v = inflator.inflate(R.layout.actionbar_refresh, this);
        mProgressBar = (ProgressBar) v.findViewById(R.id.action_refresh_progress);
        mButton = (ImageView) v.find
