Android : Issue with SearchView in AppCompat v21

I am Using AppCompat v21 with toolbar and im developing in Android Studio 0.8.14

If i plug my (4.4) phone into PC via usb and run app the searchview works as it should. I bring up the fragment and press the search icon and it allows me to type text.

However if i assemble release in gradle and install app on my device when i press the search icon nothing happens. Does not initiate the searchview. Here is my code.

My IconsFrag.java

@Override
public void onPrepareOptionsMenu (Menu menu) {
    Log.i(FRAG_TAG, "onPrepareOptionsMenu");
    MenuInflater inflater = getActivity().getMenuInflater();
    inflater.inflate(R.menu.icon_menu, menu);
    MenuItem searchItem = menu.findItem(R.id.search);

    SearchManager searchManager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);

    SearchView searchView = null;
    if (searchItem != null) {
        searchView = (SearchView) searchItem.getActionView();
    }
    if (searchView != null) {
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));
    }

}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    Log.i(FRAG_TAG, "onOptionsItemSelected");
    return super.onOptionsItemSelected(item);
}

my module build.gradle

repositories {
    mavenLocal()
    mavenCentral()
    dependencies {
        apply plugin: 'maven'
