在html中不考虑javascript函数

Question

我有一些我在一个范围变量中定义的javacript函数，如下所示：

$scope.salma = {
    selectedRestaurants: accounts.selectedRestaurants,
    findAllAccountsByRestaurant: function(restaurant) {
        angular.forEach(accounts.AllRestaurantAccounts, function(CurrentAllrestaurantAccount) {
            if(CurrentAllrestaurantAccount.nameRestaurant === restaurant) {
                accounts.currentRestaurantNumberAllAccount = CurrentAllrestaurantAccount.accountNumber;
            }
        });

        return accounts.currentRestaurantNumberAllAccount;
    },

    findAccountsOptInMAIL: function(restaurant) {
        angular.forEach(accounts.AllOptInMAILRestaurantAccounts , function(CurrentAllrestaurantAccountOptInMAIL) {
            if(CurrentAllrestaurantAccountOptInMAIL.nameRestaurant === restaurant) {
                accounts.currentRestaurantNumberOptInMAIL = CurrentAllrestaurantAccountOptInMAIL.accountNumber;
            }
        });

        return accounts.currentRestaurantNumberOptInMAIL;
    }
};

我在我的html中调用了这些函数，如下所示：

<tbody>
    <tr ng-repeat="restaurant in salma.selectedRestaurants">
        <td>{{ restaurant }}</td>
        <td>{{ salma.findAllAccountsByRestaurant(restaurant) }}</td>
        <td>{{ salma.findAccountsOptInMAIL(restaurant) }}</td>
    </tr>
</tbody>

第一个功能在html中生效但第二个功能没有生效，我不知道为什么。请问有什么建议吗？
