Приложение NFC на основе Titanium работает, только если код NFC находится в index.js

У меня проблема с ti.nfc module Appcelerator Titanium.

Это работает хорошо, только если код NFC находится в index.js, если я перехожу с index.js на другую страницу, например login.js, с этим кодом:

var login = Alloy.createController("login").getView();
login.open();

и я помещаю тот же код NFC из index.js в login.js, он не работает.

Это код, который работает:

index.js

var nfc = require('ti.nfc');
var nfcAdapter = null;
// Create the NFC adapter to be associated with this activity. 
// There should only be ONE adapter created per activity.
nfcAdapter = nfc.createNfcAdapter({
    onNdefDiscovered: handleNDEFDiscovery,
    onTagDiscovered: handleTAGDiscovery,
    onTechDiscovered: handleTECHDiscovery
});

function handleNDEFDiscovery(data){
    //Ti.API.info('NDEF DISCOVERED:: ' + data.messages[0].records[0].getPayload());
    // Our required payload fits in the first record of the first Ndef msg
    var payload = data.messages[0].records[0].getPayload();
    // First byte of payload is control byte
    // Bits 5 to 0 of the control bytes contain 
    // length of language code succeeding the control byte
    var langCodeLength = payload[0] & 0077;
    // Received NFC text data starts after textOffset bytes in payload
    var textOffset = langCodeLength + 1;
    // Payload contains byte array which needs to be converted to a string
    // nfc_text contains the exact text string sent by the sending NFC device
    var nfc_text = payload.toString().substring(textOffset);
    /* process nfc_text as required by application logic here */
}

function handleTAGDiscovery(data){
    //Ti.API.info('TAG DISCOVERED:: ' + data.messages[0].records[0].getPayload());
}

function handleTECHDiscovery(data){
    //Ti.API.info('TECH DISCOVERED:: ' + data.messages[0].records[0].getPayload());
    var tag = data.tag;
    alert('Tag ID: ' + tag.getId());
}

// Check for NFC support on device
if (!nfcAdapter.isEnabled()) {
    Ti.API.info('NFC is not enabled on this device!');
}else{        
    // Tag scans are received by the current activity as new intents. We
    // need to pass scan intents to the nfc adapter for processing.
    var act = Ti.Android.currentActivity;
    act.addEventListener('newintent', function(e) {
        nfcAdapter.onNewIntent(e.intent);
    });
    // Since we want the app to only use NFC while active in the foreground
    // We disable and enable foreground dispatch on app pause and resume respectively
    act.addEventListener('resume', function(e) {
        nfcAdapter.enableForegroundDispatch(dispatchFilter);
    });
    act.addEventListener('pause', function(e) {
        nfcAdapter.disableForegroundDispatch();
    });

    // The foreground dispatch filter specifies the types of NFC 
    // messages the app wants to receive and handle. The only entry in our case
    // specifies type ‘text/plain’ since we want to send and receive plain text     
    dispatchFilter = nfc.createNfcForegroundDispatchFilter({
        intentFilters: [
            { action: nfc.ACTION_TECH_DISCOVERED },
        ],
        techLists: [
            [ "android.nfc.tech.NfcV" ]
        ]
    });
    // This enables foreground dispatch for the first time
    nfcAdapter.enableForegroundDispatch(dispatchFilter);
}

                </application>

Кто-нибудь может мне помочь?

Большое спасибо.
