Using setZoom() after using fitBounds() with Google Maps API V3

Question

I\'m using fitBounds() to set the zoom level on my map too include all the markers currently displayed. However, when I have only one marker visible, the zoom level is 100%

Alright, I've figured it out. Apparently, the fitbounds() happens asynchronously, so you have to wait for a bounds_changed event before setting zoom works.

map = this.map.map;

map.fitBounds(this.map.bounds);
zoomChangeBoundsListener = 
    google.maps.event.addListenerOnce(map, 'bounds_changed', function(event) {
        if (this.getZoom()){
            this.setZoom(16);
        }
});
setTimeout(function(){google.maps.event.removeListener(zoomChangeBoundsListener)}, 2000);

Update: See @Nequin's answer using addListenerOnce for a better solution that doesn't require a timeout.
