AngularJS function and $scope

我在控制器中定义了如下函数：

var getTransactions = function(transactionType, partnerId) {
        return loadTexts.getTransactionTexts(transactionType, partnerId).then(function (res) {
            $scope.loadedTexts = res.data.Transactions;
        });
    };

另一个$scope函数正在调用它。现在，当我为res.data.Transactions设置console.log时，一切都会按原样记录，但当我想将数据分配给$scope变量时，它根本不起作用。(load功能后，$scope.loadedTexts为空(

$scope.load = function() {
        getTransactions($scope.TransactionTypeId, $scope.selectedPartner.Id);
    };

有什么帮助吗？

代码：

 app.controller("textsController", function ($scope, $http, autoComplete, loadTexts) {
        $scope.selectedPartner = { "Name": "", "Id": null };
        $scope.loadedTexts = [];
        .. other functions are here ...
        var getTransactions = function(transactionType, partnerId) {
            return loadTexts.getTransactionTexts(transactionType, partnerId);
        };
        $scope.load = function () {
            getTransactions($scope.transactionType, $scope.selectedPartner.Id).then(function(res) {
                $scope.loadedTexts = res.data.Transactions;
            });
        };
    });
