Custom Zoom not working

Question

I am trying to implement custom zoom in and zoom out buttons.  It doesn't seem to be working.  I was looking at one of the examples.  http://help.arcgis.com/en/webapi/javascript/arcgis/jssamples/toolbar_navigation.html.

The custom zoom in and zoom out buttons in the example dont work either so this makes me believe there is a bug.

Can anyone help me on this?  Is this a bug or am i doing something wrong?

Ok, i was thinking the zoom in button would just zoom in one level.  I didn't know you had to draw on the map for it to zoom.  Is there a way to have a custom zoom in button do what i was expecting?

This is what the + and �?? buttons in the top left corner of the map do.

You could create a zoom in button and zoom out button that call the following functions when clicked:

function zoomInLevel() {
    map.setLevel(map.getLevel() +1);
}

function zoomOutLevel() {
    map.setLevel(map.getLevel() -1);
}
