How would your map know which extent you want to zoom to? Your code would only work if your base layer changes, and the base layer was configured with a different maxExtent than the previous one.
To do what you want, you need to do something like map.zoomToExtent(evt.layer.maxExtent); which only works if you have configured your layers with a maxExtent.
