无法识别阵列的Knockout绑定

我有一个问题，我的淘汰赛没有被html识别：

<div class="row-fluid">
    <div class="span6">
        <div class="control-group">
            <fieldset>
                <legend>Rates</legend>
                <div id="creditcards-rates" class="row-fluid">
                    <p data-bind="visible: rates() == undefined || rates().length == 0">
                        No rates added yet.
                    </p>
                    <table data-bind="visible: rates() !== undefined && rates().length > 0" class="table table-striped table-condensed">
                        <thead>
                            <tr>
                                <th>Payment Status</th>
                                <th>Income Amount</th>
                                <th>Confirmed by Provider</th>
                                <th>Payment Status</th>
                                <th>Notes</th>
                                <th></th>
                            </tr>
                        </thead>
                        <tbody data-bind="foreach: rates">
                        <tr>

                            <td>
                                <input type="hidden" data-bind="value: Id, attr: { id: 'Rates[' + $index() + '].Id', name: 'Rates[' + $index() + '].Id' }" />
                            </td>
                            <td>
                                <a id="btn-remove" data-bind="click: $root.removeRate"><i class="icon icon-minus"></i></a>
                            </td>
                        </tr>
                        </tbody>
                    </table>
                    <button class="btn" data-bind="click: addNewRate"><i class="icon icon-plus"></i> Add New Payment</button>
                </div>
            </fieldset>
        </div>
    </div>
</div>

问题是数据绑定无法识别值 . 我在控制台中收到错误：

错误：语法错误，无法识别的表达式：input [data-bind ='value：Id，attr：{id：'Rates ['$ index（）'] .Id'，name：'Rates ['$ index（）' ] .Id'}'] ...）;返回一个}，bc.error = function（a）{throw new Error（“语法错误，无法识别的exp ...

我的淘汰赛是：

var Micki = Micki || {};

Micki.Electro = {

        var settings = $.extend({
            id: 0

                    });

                    //_ratesAndTiers.initFields();
                    //_campaignSpecific.initFields();
                };

                self.addNewRate = function (data, event) {
                    alert("test");
                };

                return self;
            }
        }
    }
