SDK.REST.retrieveMultipleRecords Called twice

Hi,

I call to SDK.REST.retrieveMultipleRecords a few times, But the last time he goes twice to the function.

My code:

<script type="text/javascript">
var retrievedGoalsArray = [];
var retrievedObjectivesArray = [];
var retrievedMeasuresArray = [];
window.onload = function x() { RetriveFunc.loadLists(); };
RetriveFunc = {
loadLists: function () {
alert("Hello from loadLists");

var options = "new_goalsSet?$select=new_goalId,new_auto_number,new_name";
SDK.REST.retrieveMultipleRecords("new_goal", options, RetriveFunc.retrieveGoalsCallBack, function (error) { alert(error.message); }, function () { alert("Succeeded retrieve goals");});
},
retrieveGoalsCallBack: function (retrievedGoals) {

alert("Hello from retrieveGoalsCallBack");
retrievedGoalsArray = retrievedGoals;

var options = "new_objectiveSet?$select=new_objectiveId,new_goal,new_auto_number,new_name";
SDK.REST.retrieveMultipleRecords("new_objective", options, RetriveFunc.retrieveObjectivesCallBack, function (error) { alert(error.message); }, function () { alert("Succeeded retrieve objectives"); });
},

retrieveObjectivesCallBack: function (retrievedObjectives) {
alert("Hello from retrieveObjectivesCallBack");
retrievedObjectivesArray = retrievedObjectives;

var options = "new_measureSet?$select=new_objective,new_measureId,new_auto_number,new_name";
SDK.REST.retrieveMultipleRecords("new_measure", options, RetriveFunc.retrieveMeasuresCallBack, function (error) { alert(error.message); }, function () { alert("Succeeded retrieve measures"); });

},

retrieveMeasuresCallBack: function (retrievedMeasures) {
alert("Hello from retrieveMeasuresCallBack");
retrievedMeasuresArray = retrievedMeasures;

},

};

</script>

I get twice the alert: "Hello from retrieveMeasuresCallBack", 

Why does he goes in the last call twice to retrieveMultipleRecords function?

Any idea?

Thanks!
