Unable to call cordova.exe in windows phone 8

[Divyaravind]

Hi,
I wrote the Cordova.exe code in a function hello(). The control is going inside the function but unable to call the cordova.exe.

 function openContact(successCallback, errorCallback,options){
    alert('contacts...');
   cordova.exec(sayHelloSuccess, sayHelloFailure, "Contacts", "pickContact",[ options ]);
 
}
    function sayHelloSuccess(data) {
        alert('sucess:'+data);
        $('#NameInput').value(data);
        $('#abc').text(data);
    }
 
    function sayHelloFailure(data) {
        alert('error' + JSON.stringify(data));

The alert is coming but the success alert/error alert is not coming after that.

Have implemented the contacts.cs and config.xml according to the cordova functionality.

Please help if any other settings are missed???


Thanks,
Divyaravind.
