Execute multiple http request - Parse Cloud Code - promise

Question

i have an array of stores, where the address and some other things are stored.
Now I want to iterate through this array and geocode the lat / lng coords and save them to the database.
With the code below I get double or triple entries of the same store. Do I miss something with the scope here?
Thanks!
var promises = [];
data.forEach(function (element, index)
{
var addressString = element.plz + " " + element.stadt + "," + element.adresse;
var url = encodeURI("https://maps.googleapis.com/maps/api/geocode/json?address=" +
addressString);
var promise = Parse.Cloud.httpRequest({
method: "GET",
url:url
}).then(function (http) //SUCCESS
{
var geocodedObject = new Parse.Object("GeocodedStores");
geocodedObject.set("storeID", element.id);
geocodedObject.set("Latitude", http.data.results[0].geometry.location.lat);
geocodedObject.set("Longitude", http.data.results[0].geometry.location.lng);
return geocodedObject.save(null, {
useMasterKey: true
});
},
function (http, error)
{
response.error(error);
});
promises.push(promise);
});
return Parse.Promise.when(promises);

Finally found a working solution. It looked like it was a problem with the scope. I put the code in a seperate function and added this returned promise to an array.
var fn = function(element, geocodedObject)
{
var addressString = element.plz + " " + element.stadt + "," + element.adresse;
var url = encodeURI("https://maps.googleapis.com/maps/api/geocode/json?address=" +
addressString);
Parse.Cloud.httpRequest({
method: "GET",
url: url
}).then(function(http)
{
geocodedObject.set("storeID", element.id);
geocodedObject.set("Latitude", http.data.results[0].geometry.location.lat);
geocodedObject.set("Longitude", http.data.results[0].geometry.location.lng);
geocodedObject.set("address", addressString);
return geocodedObject.save(null, {
useMasterKey: true
});
});
}
var promises = [];
for (var k = 0;k<data.length;k++)
{
var geocodedObject = new Parse.Object("GeocodedStores");
promises.push(fn(data[k], geocodedObject));
}
Parse.Promise.when(promises).then(function () {
response.success("DONE");
});
