Google Maps API - Trouble with Arrays and InfoWindows

Sorry if this is trivial, but I am new to JS and have been at this problem for a few hours to no avail.

function initialize() {
    geocoder = new google.maps.Geocoder();
    var latlng = new google.maps.LatLng(-34.397, 150.644);
    var myOptions = {
    zoom: 12,
    center: latlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}

var markersArray = [];
var infowindowArray = [];

function addMarker(location) {
    marker = new google.maps.Marker({
    position: location,
    map: map
    });
    markersArray.push(marker);
}

function addInfowindow(string) {
    infowindow = new google.maps.InfoWindow({content: string});
    infowindowArray.push(infowindow);
}

function findvenues(latitudelongitude) {
$.get("venuefinder.php", { latlong:latitudelongitude.Ka+","+latitudelongitude.La }, function(data){
    var myObject = eval('(' + data + ')');
    for(x in myObject.response.venues){
        var latlonglocation = new google.maps.LatLng(myObject.response.venues[x].location.lat,myObject.response.venues[x].location.lng);
        addMarker(latlonglocation);
        addInfowindow(myObject.response.venues[x].name);
        google.maps.event.addListener(markersArray[x], 'click', function() {infowindowArray[x].open(map,markersArray[x]);});
        console.log(markersArray[x],infowindowArray[x]);
    }
});

When findvenues is called, the infowindow click events should be added. When I click the icons, the same infowindow of the last element in the array of infowindows always opens.

However, if I manually enter in the following code, it works:

google.maps.event.addListener(markersArray[0], 'click', function() {infowindowArray[0].open(map,markersArray[0]);});
google.maps.event.addListener(markersArray[1], 'click', function() {infowindowArray[1].open(map,markersArray[1]);});

I need this to be dynamic though... What am
