Between the "var pushpin" and "map.entities.push..." lines, add what I have below. That'll get you started. Basically, you are adding an event handler.

Note that the event is added to the "pin" in this case - but can be added to other objects such as the "infobox" if we had one here. There are only a few supported events - check docs. But you can do some neat stuff once you've wired the event. Have fun!

CODE:

var pushpin = new Microsoft.Maps.Pushpin(location);

Microsoft.Maps.Events.addHandler(pushpin, 'mouseover', function () {
alert("The mouse went over the pin");});               

map.entities.push(pushpin);

Llewellyn answer is valid. Another approach, is put a value for 'typeName' parameter in the pushpin line:

var pushpin = new Microsoft.Maps.Pushpin(location, {typeName: 'pin123'});
map.entities.push(pushpin);

next, using jQuery, you can add elements, or catch events:

$(".pin123" ).mouseover(function() { alert("hey!"); });
