info window not showing reverse geocoded address Google Maps V3 - google-maps

Question

I'm coding a script that allows you to place a marker based on where you mouse click. I got that down. However, I cannot seem to get the infowindow to pop up when I pass in the reverse geocoded lat and lng. Could someone help me? Thanks!
Here is my code:
var geocoder;
function initialize()
{
geocoder = new google.maps.Geocoder();
var event = google.maps.event.addListener;
// intializing and creating the map.
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(-25.363882, 131.044922),
mapTypeId: google.maps.MapTypeId.TERRAIN
};
var map = new google.maps.Map(document.getElementById('map'),
mapOptions);
event(map,'click',function(e){
var marker = placeMarker_and_attachMessage(e.latLng,map,count);
});
} // end of initalize.
/* place down marker based on where you click the mouse over a certain area on the map.
An infowindow should appear with the location of your marker.
*/
function placeMarker_and_attachMessage(position,map,num)
{
var event = google.maps.event.addListener;
var marker = new google.maps.Marker({
position: position,
map: map
});
var infowindow = new google.maps.InfoWindow({
content: info_text(position)
});
event(marker,'mouseover',function(){
infowindow.open(map,this);
});
event(marker,'mouseout',function(){
infowindow.close();
});
} // end of function.
// Takes in the position passed by the 'placeMarker_and_attachMessage' function and returns a human readable string
function info_text(position)
{
var location = position;
var latlngStr = location.split(',',2);
var lat = parseFloat(latlngStr[0]);
var lng = parseFloat(latlngStr[1]);
var latlng = new google.maps.LatLng(lat,lng);
geocoder.geocode({'latLng': latlng}, function(results, status)
{
if (status == google.maps.GeocoderStatus.OK)
{
return results;
}
else
{
alert('could not pinpoint location');
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);

In the code you posted, count is not defined in
var marker = placeMarker_and_attachMessage(e.latLng,map,count);
