                } else {
                    //Here i want to add CURRENCY filter "| currency"
                    return amount;

您可以使用数字过滤器。请试试

.filter('amount', function($filter) {
            return function(amount) {
                if (!amount) {
                    return 'Invalid Amount';
                } else {
                    //Here i want to add CURRENCY filter "| currency"
                    var newAmount = $filter('number')(amount, 2);
                    return "$"+ newAmount;
                }
            }
  })

或类似

return $filter('currency')(amount, "$", 2);
