Angularjs translate dropdown from i18n using ng-repeat

Question

My English translation of the i18n json file is assets/i18n/en.jsonas follows (this is a translation into English, I have several other files for other languages ​​in the same directory):

{
  "project": {
    "SPONSORINFO": {
      "MAIN" : "Select the Sponsor Name",
      "SPONSORLIST": [
        {"spons" :"SponsorName 1" },
        {"spons" :"SponsorName 2" }
      ]
    }
  }
}

and here is my html view:

<div class="form-group" >
    <label for="form-field-select-1" translate="project.SPONSORINFO.MAIN">
    </label>
    <select class="form-control"  ng-model="myModel.sponsors">
        <option ng-repeat="s in spons.SPONSORLIST" value="{{s.spons}}">{{s.spons}}</option>
    </select>
</div>

translate="project.SPONSORINFO.MAIN" in shortcut fairly displays the value "Choose sponsor name . " No problem on this side.

Question:

How to ng-repeat items in a SPONSORLIST drop-down menu?
what I have now does not show anything, as you can guess.

edit:

I have a global configuration in my main.js as shown below:

app.config(['$translateProvider',
function ($translateProvider) {

    // prefix and suffix information  is required to specify a pattern
    // You can simply use the static-files loader with this pattern:
    $translateProvider.useStaticFilesLoader({
        prefix: 'assets/i18n/',
        suffix: '.json'
    });

    // Since you've now registered more then one translation table, angular-translate has to know which one to use.
    // This is where preferredLanguage(langKey) comes in.
    $translateProvider.preferredLanguage('en');

    // Store the language in the local storage
    $translateProvider.useLocalStorage();

}]);

but I have no links in my view controller regarding translation.

change 2:

, mainCtrl.js, , index.html:

app.controller('AppCtrl', ['$rootScope', '$scope', '$state', '$translate', 
function ($rootScope, $scope, $state, $translate) {

    $scope.language = {
        // Handles language dropdown
        listIsOpen: false,
        // list of available languages
        available: {
            'en': 'English',
            //'it_IT': 'Italiano',
            'de_DE': 'Deutsch'
        },
        // display always the current ui language
        init: function () {
            var proposedLanguage = $translate.proposedLanguage() || $translate.use();
            var preferredLanguage = $translate.preferredLanguage();
            // we know we have set a preferred one in app.config
            $scope.language.selected = $scope.language.available[(proposedLanguage || preferredLanguage)];
        },
        set: function (localeId, ev) {
            $translate.use(localeId);
            $scope.language.selected = $scope.language.available[localeId];
            $scope.language.listIsOpen = !$scope.language.listIsOpen;
        }
    };

    $scope.language.init();

update 2 ( , ):

, en.json, .

$http.get('assets/i18n/en.json').success(function(data) {
     $scope.projectJSON = data;
});

ng-repeat:

<option ng-repeat="s in projectJSON.project.SPONSORINFO.SPONSORLIST" value="{{s.spons}}">{{s.spons | translate}}</option>

, , . , :

$scope.language.selected = function (localeId) {
$translate.use(localeId);
    $http.get('assets/i18n/'+localeId+'.json').success(function(data) {
        $scope.projectJSON= data;
    });
};

():

var lang = $translate.use();
$http.get('assets/i18n/'+lang+'.json').success(function(data) {
    $scope.projectJSON= data;
});
