Extjs add multiple records in the store

Question

In my ExtJs app I have to save, after made some editing, multiple records in the store (as many records as it is the number of beaconsCounter) and after reload the store and close the dialog, but I don't know why, nothing happens. I am a newbie in Extjs so I don't know what it is incorrect in my code.

onSaveClick: function (button) {
              var dialog, store, beaconToSave , window;
              var numberOfBeaconPositionated, beaconsCounter, name, uuid, major, minor, originalNameValue;
              var arrayOfLong, arrayOfLat, nameString;

              window = button.up('window')
              dialog = window.down('form');
              dialog.updateRecord();
              beaconToSave = dialog.getRecord();
              store = beaconToSave.store;

              numberOfBeaconPositionated = this.lookupReference('beaconNumbers').getValue();
              name = beaconToSave.get('name');
              uuid = beaconToSave.get('uuid');
              major = beaconToSave.get('major');
              minor = beaconToSave.get('minor');
              latitude = this.lookupReference('beaconLatitude').getValue();
              longitude = this.lookupReference('beaconLongitude').getValue();

              if((name === "")||(uuid === "")){
                   Ext.Msg.alert(Strings.errorTitle, Strings.errorFieldMissing, Ext.emptyFn);
              }else if ((major === 0)||(minor === 0)){
                   Ext.Msg.alert(Strings.errorTitle, Strings.errorMajMin, Ext.emptyFn);
              }else if((longitude === "0")||(latitude === "0")){
                   Ext.Msg.alert(Strings.errorTitle, Strings.errorNoBeacons, Ext.emptyFn);
              }else{
                  nameString = name.split("-");

                  if((name.indexOf('-%min%') >= 0) || (name.indexOf('-%maj%') >= 0) || (name.indexOf('-'+major+'-'+minor) >= 0) || (nameString[1]!=null)) {
                     originalNameValue=nameString[0];
                  }else{
                     originalNameValue = name;
                  }

                  uuid = beaconToSave.get('uuid');
                  major = beaconToSave.get('major');
                  minor = beaconToSave.get('minor');
                  latitude = this.lookupReference('beaconLatitude').getValue();
                  longitude = this.lookupReference('beaconLongitude').getValue();
                  arrayOfLong = longitude.split(",");
                  arrayOfLat = latitude.split(",");
                  store = beaconToSave.store;
                  beaconsCounter = numberOfBeaconPositionated;

                  while(beaconsCounter > 0 ){

                      newRecord = beaconToSave.copy();
                      name=originalNameValue.concat("-"+major+"-"+minor);
                      newRecord.set('name',name);
                      newRecord.set('latitude',arrayOfLat[beaconsCounter-1]);
                      newRecord.set('longitude',arrayOfLong[beaconsCounter-1]);
                      newRecord.set('minor',minor);


                       if ( !store && !Ext.isEmpty(savedStore)){
                                 store = savedStore;
                             }
                             if (store) {
                                 if (newRecord.phantom) {
                                     store.add(newRecord);
                                 }
                                 store.sync({
                                     failure: function (batch) {
                                         store.rejectChanges();
                                         savedStore = store;
                                         if ( batch.exceptions[0].getError().status){
                                             if ( batch.exceptions[0].getError().status == 409){
                                                 Traccar.app.showError(this.getTitle() + Strings.errorAddDuplicate);
                                             }else if(batch.exceptions[0].getError().status == 400){
                                                 Traccar.app.showError(this.getTitle() + Strings.errorAddDatabase);
                                             }else{

                                     },

                                 this.closeView();
                             }
                      minor++;
                      beaconsCounter--;
                  }

              }
     },

You shouldn't use newRecord = beaconToSave.copy() because this make new record with same id. Use newRecord = {'name':name,'latitude':arrayOfLat[beaconsCounter-1],'longitude',arrayOfLong[beaconsCounter-1],'minor',minor}; instead
