geocoder.geocode works only in particular condition

Question

This code works only with the 2 alerts active in the script block, if you comment the first or the second alert the geocode function doesn't work. It is a simple asp.net page that try to obtain latitude and longitude from an address, in this case hard coded:

            var geocoder = new google.maps.Geocoder();

            alert("before");  //if you remove this doesn't work
            geocoder.geocode({ 'address': "Cagliari, Italy" }, function (results, status) {
                if (status == google.maps.GeocoderStatus.OK) {
                    $('#<%= TxbLatitudine.ClientID %>').val("a");
                } else {
                    $('#<%= TxbLongitudine.ClientID %>').val("not OK");
                }
            });
            alert("after");  //if you remove this doesn't work
        }
    </script>
</body>
</html>

Answer 1

I replaced the asp:Button with html input button:

<input id="Button1" type="button" value="Find..." onclick="javascript: findLocation();" />

the first one caused page postback that interfered with the client script block function.
