google.maps.event.addListener( dom_obj, 'click', function() {

    alert( 'Test - called from addListener' );
    console.log( dom_obj );
} );
jQuery( zoom_in ).click(
    function() {

        alert( 'Test - called via jQuery click function' );
        console.log( dom_obj );
        return false;
    }
);
