            Payement.saveContratEtudant($scope.nb_piece1,$scope.nb_piece2,$scope.shortadresse,$scope.govClt,$scope.villeClt,localiteClt,$scope.voieClt,$scope.cod_logem,$scope.adresse_logem,$scope.govLogem,$scope.gelgLogem,$scope.dateDelivra, $scope.dateEffet, $scope.dateExp, $scope.nomAssure,$scope.prenomAssure,$scope.piece2,$scope.numDocument,$scope.typeContrat,$scope.natureContrat,$scope.piece1, $scope.dateNais,$scope.email,$scope.phone, $scope.IdTrans,$scope.reference, $scope.numDocuemnt, $scope.codePostal, $scope.adresse,$scope.typedocu,$scope.sexeClt,$scope.tarif,$scope.frais,$scope.tva,$scope.tcc ,function (data) {
               console.log("test saveContrat")
                //console.log("date:",date)
                if (data.data.state_code == 200){
                    $scope.local_ = data;
                    console.log($scope.local_.data.data);
                    $state.go('map')
                } else {
                     $ionicPopup.alert({
                        title: "Alert",
                        template: data.data.message
                    });
                }
            });

It simply means that in this portion of code :

.then(function (response) {
    callback(response);  // <- HERE
    // $ionicLoading.hide();
    console.log("ajout ");
});

You are calling the function named "callback". But it's not defined. Probably because nothing is passed as param in the last param of this function :

saveContratEtudant: function (_nb_piece1,_nb_piece2,_shortadresse,_govClt,_villeClt,_localiteClt,_voieClt,_cod_logem,_adresse_logem,_govLogem,_gelgLogem, _dateDel,_dateEffet,_dateExp,_nomAssure, _prenomAssure ,_piece2,_numDocument,_typeContrat,_natureContrat,_piece1,_dateNais,_email,_phone,_IdTrans,_reference,_numDocuemnt,_codePostal,_adresse,_typedocu,_sexeClt,_tarif,_frais ,_tva, _tcc, callback) {

Splitted similar line :

saveContratEtudant: function (_nb_piece1,
                              _nb_piece2,
                              _shortadresse,
                              _govClt,
                              _villeClt,
                              _localiteClt,
                              _voieClt,
                              _cod_logem,
                              _adresse_logem,
                              _govLogem,
                              _gelgLogem, _dateDel,
                              _dateEffet,
                              _dateExp,
                              _nomAssure,
                              _prenomAssure ,
                              _piece2,
                              _numDocument,
                              _typeContrat,
                              _natureContrat,
                              _piece1,
                              _dateNais,
                              _email,
                              _phone,
                              _IdTrans,
                              _reference,
                              _numDocuemnt,
                              _codePostal,
                              _adresse,
                              _typedocu,
                              _sexeClt,
                              _tarif,
                              _frais,
                              _tva,
                              _tcc,
                              callback // <- HERE
                              ) {

You should check if it's defined before calling it. Or check if your code provided really the function.

Pro tip : you should not have that much arguments in function.

So you should try like this :

    .factory('Payement', function ($http, $ionicLoading) {
        return {
            saveContratEtudant: function (params, callback) {
                $http({
                    method: 'POST',
                    url:SAVE_ETUDIANT,
                    timeout: 10000,
                    data: params,
                }).then(function (response) {
                    callback(response);
                   // $ionicLoading.hide();
                    console.log("ajout ");
                });
            }
        };
    })

And call it like this :

Payement.saveContratEtudant($scope, function (data) {...})
