change content infowindow maps v3

Question

I am trying to make it possible to change the content that shows up inside a DIV that is the content of an infowindow. I have been able to change the content from Hello to YO in

Answer 1

I found the above accepted answer didn't work as I had to use setContent() as follows:

google.maps.event.addListener(drawingManager, 'overlaycomplete', function (event) {
    if (event.type == google.maps.drawing.OverlayType.MARKER) {
        //event.overlay.setTitle("Hello");
        var infowindow = new google.maps.InfoWindow({
            content: '
Hello
',
            maxWidth: 10
        });
        google.maps.event.addListener(event.overlay, 'click', function () {
            infowindow.open(map, event.overlay);
        });
    }
});
function updateContent() {
    infowindow.setContent("Yo");
}
