Android : SearchView Not call onOptionsItemSelected

"Error" Well Strange Other times I've done it and never tive this problem ...

My searchview not call onOptionsItemSelected if i put "appname:actionViewClass="android.support.v7.widget.SearchView" on menu.

Manifest

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />
 <activity
            android:name=".DashBoardActivity"
            android:label="">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

DashBoardActivity

@Override

        MenuItem searchItem = menu.findItem(R.id.action_search);
        mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);
        return true;
    }

    @Override

        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.

        int id = item.getItemId();
        switch (id)
        {
        case R.id.action_search:
            mSearchView
            .setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {
                @Override
                public void onFocusChange(View v, boolean hasFocus) {
                    if (hasFocus) {
                        ToastMensagem("Digite um endereço.");
                    } else {
                        BuscarEndereco(mSearchView.getQuery().toString());
                    }
