code works in chrome on my PC but doesn't work in my devices

I am using Sencha Touch and trying to get data from a remote server

Here is my store

Code:

Ext.define('webTrak.store.NoiseStore', {
        extend: 'Ext.data.Store',
        requires: ['webTrak.model.noiseChunk', 'Ext.data.reader.Xml'],
        config:{
            autoLoad: true,
            storeId: 'NoiseStore',
            model: 'webTrak.model.noiseChunk',
            proxy: {
                type: 'ajax',
                //url: "http://ift.tt/1fbg3po'http%3A%2F%2Fwebtrak.bksv.com%2Fmel%2Fdata%2F46610526'&format=json&diagnostics=true&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=",
                url: 'http://ift.tt/1fuX97P',
                //url:'app/store/now.xml',
                reader: {
                    type: 'xml',
                    //rootProperty: 'results',
                    record: 'data'
                }
            }
        }
      
    });

and my controller

Code:

noiseStore.load({
                callback: function (records, operation, success) {
                    myop = records;
    
                    if (!success) {
                        Ext.Msg.alert('Failed!', records[0]);
                    }
                    else
                    {
                        Ext.Msg.alert('Success!', $(records[0].raw).html());
                    }
    
                    var lines = $(records[0].raw).html().split('\n');
                    //var lines = records[0].raw.innerHTML.split('\n');
                    Ext.Msg.alert('number of lines', lines);
    
    
                    Ext.Object.each(lines, function (key, value, myself) {
                        //window.setInterval(function () { }, 1000);
                        Ext.Function.defer(function () {
                            var fields = value.split(',');
                            var isNoise = fields[0];
                            if (isNoise === 'noise') {
                                console.log('noise = ' + fields[5]);
                                Ext.Msg.alert('noise', fields[5]);
    
                                var locid = fields[3];
                                var noisevalue = fields[5];
    
                                var overlayTmp = new Ext.Template('<div class="overlay">{noiseValue}</div>', { compiled: true });
                                overlayTmp.compile();
                                var overlayHtml = overlayTmp.apply({ noiseValue: noisevalue });
    
                                var tempOverLay = sensorSet[locid];
                                tempOverLay.onRemove();
    
                                sensorSet[locid].setValues({
                                    content: overlayHtml
                                });
    
                                sensorSet[locid].onAdd();
                                sensorSet[locid].draw();
                            }
                            else {
                                console.log('radar = ' + fields[10]);
                            }
                        }, 2000);
                        //window.setInterval(function () {
                          
                        //}, 1000);
    
                      
                    });
    
                }
            });
