My call in phonegap in WP8 to consuming service wcf works only in index.html file. If i call in the .js file i get error GetListaMunicipios was not called.

my call:

$.support.cors = true;

$.mobile.allowCrossDomainPages = true;

$.ajax("http://localhost:56976/MunicipiosService.svc/ListaMunicipios?callback=?",{

beforeSend: function (xhr) {

// $.mobile.showPageLoadingMsg();

alert('beforeSend');

},

complete: function () {

// $.mobile.hidePageLoadingMsg();

alert('complete');

},

contentType: 'application/json; charset=utf-8',

dataType: 'jsonp',

type: 'GET',

crossDomain: true,

cache:true,

jsonp: 'callback',

        jsonpCallback: 'GetListaMunicipios',

error: function (xhr, ajaxOptions, thrownError) {

alert('not ok 1 ' + xhr.status);

alert('not ok 2 ' + xhr.responseText);

alert('not ok 3 ' + thrownError);

},

success: function (data) {

alert('success');

}

});

I have no ideia what is wrong because its work in html. Thanks for help
