How to update objects on a Parse.com class with CloudCode?

I use Parse.com for the backend of my app. I use Cloud Code. I have 2 classes :

• AllStudents : nameID, firstName, address, city, bike, description
• Details : NameID, Bike, Description

AllStudents class : columns nameID, firstName, address, city are populated. Columns bike and description class are empty.

Details class : columns NameID, Bike, Description are populated.

I want to populate the columns bike and description of AllStudents class with columns Bike and Description (Details class), thus to update each rows of my AllStudents class. As nameID and NameID have the same value, I use it to "join" the classes.

I know that I could use Relational Datas but for the purpose of my app I need to populate the AllStudents class.

Here is my code. The problem is that the columns bike and description are well populated but with the same value : for bike:"Mountain Bicycles" and for description:"Blue and red". It's the value of my last row in Details class. I don't understand why, do you have any idea ?

Parse.Cloud.define("MyFunction", function(request, response) {

var Students = Parse.Object.extend("AllStudents");
var studentsQuery = new Parse.Query(Students);
var Details = Parse.Object.extend("Details");
var detailsQuery = new Parse.Query(Details);

  studentsQuery.matchesKeyInQuery("nameID", "NameID", detailsQuery);
  studentsQuery.find({
    success: function(resultats) {
      for (var i = 0; i < resultats.length; i++) { 
        var object = resultats[i];
        studentsQuery.get(object.id, {
          success: function(resultat) {
            detailsQuery.equalTo("NameID", object.get('nameID'));
            detailsQuery.find({
              success: function(results) {
              var objectif = results[0];
              resultat.set({ bike: objectif.get('Bike'), description: objectif.get('Description')});
              resultat.save();
              }
            });
          },
          error: function(object, error) {
          }
        });
      }
    }
  });

}); 

Thanks for your help !
