Hi my button event listener is not working.It was working till yesterday correctly but now it is not working var GlobalVar=new Array(); GlobalaVar=["PHP Web Developer","Drupal Developer"]; var win5 = Titanium.UI.createWindow({ title : 'Tab 5', backgroundColor : '#fff' });

     var searchbyjob = Titanium.UI.createTextField({
hintText : 'Search By Job',
top : 25,
borderWidth : 0,
width : 350,
left : 60,
height : 60,
font : {
    fontSize : 14,
    fontColor : '#262626',
    fontFamily : 'Helvetica'
},
autoCorrect : false,
//autocapitalization : Titanium.UI.TEXT_AUTOCAPITALIZATION_ALL,
//  keyboardType:Titanium.UI.KEYBOARD_NUMBER_PAD
       });
          win5.add(searchbyjob);
        var searchbycompany = Titanium.UI.createTextField({
hintText : 'Search By Company',
top : 100,
borderWidth : 0,
width : 350,
left : 60,
height : 60,
font : {
    fontSize : 14,
    fontColor : '#262626',
    fontFamily : 'Helvetica'
},
autoCorrect : false,
autocapitalization : Titanium.UI.TEXT_AUTOCAPITALIZATION_ALL
      });
          win5.add(searchbycompany);
  // Create the search button from our search.png image
    var btnSearchcompany = Titanium.UI.createButton({
backgroundImage : 'images/search.png',
top : 112,
width : 80,
height : 30,
right : 75,
borderRadius : 3
      });
      win5.add(btnSearchcompany);
      / / Create the search button from our search.png image
     var btnSearchjob = Titanium.UI.createButton({
backgroundImage : 'images/search.png',
top : 37,
width : 80,
height : 30,
right : 75,
borderRadius : 3
     });
      win5.add(btnSearchjob);
       var tableView2 = Titanium.UI.createTableView();
      win5.add(tableView2);

      btnSearchjob.addEventListener('click', function(e) {
      searchyql();


      });
       function searchyql(){
var n = 0;
var count = 0;
var a = GlobalVar.length;
for (var i = 0; i < GlobalVar.length; i++) {
        alert(GlobalVar[i]);
    n++;

    if (GlobalVar[i] == searchbyjob.value) {
        btnSearchjob.hide();
        btnSearchcompany.hide();
        searchbyjob.hide();
        searchbycompany.hide();
        count++;
        var Row = [];
        Titanium.Yahoo.yql('select * from html where url="http://afghanskills.com/all-jobs.php"  and xpath="//tbody/tr[' + n + ']/td/font"', function(e) {
            var results = e.data.font;

            for (var i = 0; i < results.length; i++) {
                var rss = results[i];
                var rssRow = Titanium.UI.createTableViewRow({
                    top : 200,
                    height : 45,
                    className : 'rssrow'

                });
                var titleLabel = Titanium.UI.createLabel({
                    text : rss.content,
                    font : {
                        fontSize : 16,
                        fontWeight : 'bold'
                    },
                    width : 'auto',
                    top : 5,
                    left : 40,
                    height : 16
                });

                rssRow.add(titleLabel);

                Row.push(rssRow);
            };

            tableView2.setData(Row);

        });
    } else if (n == a - 1 && count == 0) {
        alert("Your Job IS NOT FOUND");
    }
}

} win5.open();

There are two button on it and which one is not working...

var btnSearchcompany = Titanium.UI.createButton({   //button 1 does not have any event listener
backgroundImage : 'images/search.png',
top : 112,
width : 80,
height : 30,
right : 75,
borderRadius : 3
      });
      win5.add(btnSearchcompany);
      / / Create the search button from our search.png image
     var btnSearchjob = Titanium.UI.createButton({ //button 2 has event listener.
backgroundImage : 'images/search.png',
top : 37,
width : 80,
height : 30,
right : 75,
borderRadius : 3
     });

for button 2 click event.. put the log message on click and put that console message here... and also confirm that its tapped properly.. there is no hidden view also.
