Soap call fails for authentication header Titanium Appcelator

I want to consume ASMX service in my titanium project, for that I have used the Kitchen Sink Nook project and it works well for the currency convertor asmx webservice and it doesn't have the authentication header.

But I have authentication header for my client webservice, I have tested the below webservice in SOAP UI and it works perfect. But I don't get the solution for Titanium SOAP Call.

Calling_class.js
 
Titanium.include('suds.js');
var window = Ti.UI.createWindow({
    title:"Web Service Test",
    backgroundColor:"#FFF",
    exitOnClose:true
 
});
var label = Ti.UI.createLabel({
    top: 10,
    left: 10,
    width: 'auto',
    height: 'auto',
    text: 'Contacting currency rates web service...'
});
 
var bouton = Titanium.UI.createButton({
 
    title:"Test",
    bottom:20,
    height:120,
    width:135,  
});
 
window.add(label);
 
 
var url = "http://192.168.15.45:8082/CrmAppointments.asmx";
var callparams = {
    AppointmentNumber: 'APP-00000003-H042S5',
    UserId: '4'
};
 
var suds = new SudsClient({
    endpoint: url,
    targetNamespace: 'http://tempuri.org'
});
 
bouton.addEventListener("click", function(e){
 
try {
    suds.invoke('BookAppointmentFromWCF', callparams, function(xmlDoc) {
 console.log('response : '+ this.responseText);
        var results = xmlDoc.documentElement.getElementsByTagName('BookAppointmentFromWCF');
        if (results && results.length>0) {
            var result = results.item(0);
            label.text = '1 Euro buys you ' + results.item(0).text + ' U.S. Dollars.';
        } else {
            label.text = 'Oops, could not determine result of SOAP call.';
        }
    });
} catch(e) {
    Ti.API.error('Error: ' + e);
}
});
window.add(bouton);
window.open();

    if (typeof body !== 'string') {

    config.envelopeBegin = ebegin.replace('PLACEHOLDER', config.targetNamespace);
 
    //Build Soapaction header - if no trailing slash in namespace, need to splice one in for soap action
    var soapAction = '';
    if (config.targetNamespace.lastIndexOf('/') != config.targetNamespace.length - 1) {

    var xhr = getXHR();

      _callback.call(this, xmlDomFromString(this.responseText));

        xhr.setRequestHeader('SOAPAction', soapAction);
        xhr.send(config.envelopeBegin+body+config.envelopeEnd);
        console.log(config.envelopeBegin+body+config.envelopeEnd);
  };
}

The main methods in this code is the var config = extend({ which is the client configuration for SOAP xml. When I execute I get this output:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>Server was unable to process request. ---> Object reference not set to an instance of an object.</faultstring>
<detail />
</soap:Fault>
</soap:Body>
</soap:Envelope>

I've checked SOAP UI for testing the webservice by removing the authentication header, and it gives me the same exact error like in Titanium.

My question is how would I can pass the Authentication header with username and password values?

I have tried using it before and after xhr.Open(), but still I get the same error. I used it like this xhr.setUsername('Infrab') xhr.setPassword('ZxH35oCeXnA')
