Ionic View : $http call impossible?


I have an issue with Ionic View app.
My app is own a page that display a HTML content given by a web service.
It works on local, on real device (after building) but not from Ionic View App.

Is there a limit with $http call in Ionic View?

Here is my Code :

Template :

<ion-view ng-init="hideFooter()">
        <div ng-bind-html="WSData"></div>

Controler :

.controller('TestCtrl', function($scope, WSService) {
    WSService.getInfo().success(function(data) {
            $scope.WSData = data.mydata;

Service :

var getInfo = function() {
                var url ="http://XXXXXXXXXX.php?callback=JSON_CALLBACK";
                return $http({
                    method: 'JSONP',
                    url: url
