Using Ti.App.Properties

Hi everyone, may I know how do I use the Ti.App.Properties to retrieve my information from the database once I clicked the submit button and it will loop so that everytime I clicked the submit button, it will loop to the next question from my database.

var self = Titanium.UI.currentWindow;
 
    var db = Ti.Database.install('quizDB1.sqlite', 'quizDB');
    db = Ti.Database.open("quizDB");
 
  var questionRS = db.execute('SELECT QuestionRecordId,QuestionText,ChoiceText1,ChoiceText2,ChoiceText3,CorrectChoice, Score FROM BTTQuestion WHERE QuestionRecordId = ' + Ti.App.Properties.getString('questionRecordID'));
 
 
 
 var questionTableData = [];
 
  var questionText = questionRS.fieldByName('QuestionText');
  var choiceText1 = questionRS.fieldByName('ChoiceText1');
    var choiceText2 = questionRS.fieldByName('ChoiceText2');
      var choiceText3 = questionRS.fieldByName('ChoiceText3');
 
  var correctChoice = questionRS.fieldByName('CorrectChoice');
  var questionTableRow = Ti.UI.createTableViewRow({height:100,className:'forumEvent'});
  var questionRecordId = questionRS.fieldByName('QuestionRecordId');
  var labelQuestion = Ti.UI.createLabel({color:'#000',backgroundColor:'yellow',font:{fontsize:'28'},width:200});
  labelQuestion.text = questionText;
 
Ti.App.Properties.setString ('newQuestion' + 2);
 
var submitbtn = Titanium.UI.createButton({
    top : '37.5%',
    left : "40%",
    height : "30%",
    width : "40%",
    backgroundImage : 'Images/submitbtn.png'
});
 
 
var radioButton2 = Titanium.UI.createButton({
    top : '37.5%',
    left : "40%",
    height : "30%",
    width : "40%",
    backgroundImage : 'Images/rdBtn_Selected.png'
});
 
 
 
  questionTableRow.add(labelQuestion);//add the new labelQuestion into the questionTableRow
  questionTableData.push(questionTableRow); //add the nw questionTableRow into the questionTableData
 
  questionTableRow = Ti.UI.createTableViewRow({height:100,className:'forumEvent'});
  var labelChoice1 = Ti.UI.createLabel({color:'#000',backgroundColor:'white',font:{fontsize:'28'},width:200});
  labelChoice1.text = choiceText1;
  if (correctChoice=="1"){labelChoice1.isCorrect=1;}else{labelChoice1.isCorrect=0;}
 
     radioButton2.addEventListener('click',function(e){
 
    radioButton2.backgroundImage = 'Images/rdBtn_Selected.png';
 
     if (choiceText1.isCorrect=="1"){
     alert('Your choice is right');
 
     }else{
     alert('Your choice is wrong')  ;
 
     }
 
 
 
  }) 
  questionTableRow.add(labelChoice1);//add the new labelChoice into the questionTableRow
  questionTableData.push(questionTableRow); //add the nw questionTableRow into the questionTableData
 
  questionTableRow = Ti.UI.createTableViewRow({height:100,className:'forumEvent'});
  var labelChoice2 = Ti.UI.createLabel({color:'#000',backgroundColor:'white',font:{fontsize:'28'},width:200});
  labelChoice2.text = choiceText2;
  if (correctChoice=="2"){labelChoice2.isCorrect=1;}else{labelChoice2.isCorrect=0;}
 
     questionTableRow.addEventListener('click',function(e){
     if (e.row.children[0].isCorrect=="1"){
     alert('Your choice is right');
     }else{
     alert('Your choice is wrong')  ;
 
     }
 
  }) 
  questionTableRow.add(labelChoice2);//add the new labelChoice into the questionTableRow
  questionTableData.push(questionTableRow); //add the nw questionTableRow into the questionTableData
 
  questionTableRow = Ti.UI.createTableViewRow({height:100,className:'forumEvent'});
  var labelChoice3 = Ti.UI.createLabel({color:'#000',backgroundColor:'white',font:{fontsize:'28'},width:200});
  labelChoice3.text = choiceText3;
  if (correctChoice=="3"){labelChoice3.isCorrect=1;}else{labelChoice3.isCorrect=0;}
 
 
    questionTableRow.addEventListener('click',function(e){
     if (e.row.children[0].isCorrect=="1"){
     alert('Your choice is right');
     }else{
     alert('Your choice is wrong')  ;
 
     }
 
  })
  questionTableRow.add(labelChoice3);//add the new labelChoice into the questionTableRow
  questionTableData.push(questionTableRow); //add the nw questionTableRow into the questionTableData
 
 
  var tableView = Ti.UI.createTableView({backgroundColor:'white',data:questionTableData});
    self.add(tableView);
    self.add(submitbtn);
 
submitbtn.addEventListener('click',function(e){
    //var window = Ti.UI.createWindow({
        Ti.App.Properties.getString('newQuestion'),
 
        //url : 'details.js',
        //backgroundColor: 'black',
        //fullscreen: false,
    //});
    window.open();
