无法在Knockout.js中绑定具有复杂对象的视图

我正在尝试使用KnockOut.js绑定视图上的复杂对象 . 在不使用overservable（）和observableArray（）的情况下，我能够将对象与视图绑定 . 但是当我实现observable（）时，返回的结果在我的javascript viewmodel中添加了observable对象，并且我的视图无法绑定viewmodel .

这是服务器端的代码实现：

Model:

    public class SurveyQuestion
    {
        public string QuestionNumber { get; set; }
        public string Question { get; set; }
        public QuestionType QuestionTypeStructure { get; set; }
        public IList OptionsList { get; set; }
    }

    public enum QuestionType
    {
        CheckBox,
        RadioButton,
        TextBox,
        AdvancedCheckBox,
        AdvancedRadioButton
    }

    public class Options
    {
        public string OptionValue { get; set; }
    }

    ViewModel:

    public class SurveyCollection
    {
        public IList SurveyList { get; set; }
    }

以上通用的结果在下面的json中得出

{"SurveyList":[

    {"QuestionNumber":"1","Question":"Write down the second consonant after the second vowel?","QuestionTypeStructure":2,"OptionsList":[{"OptionValue":"F"},{"OptionValue":"G"},{"OptionValue":"C"},{"OptionValue":"B"}]},

    {"QuestionNumber":"2","Question":"Complete the following letter series: ZYX/ VW/ UTS/ QR/ PON/ LM/ KJI?","QuestionTypeStructure":1,"OptionsList":[{"OptionValue":"GB"},{"OptionValue":"IJ"},{"OptionValue":"GH"},{"OptionValue":"LM"}]},

    {"QuestionNumber":"3","Question":"What would be the numrical digits to represent the word VOWEL when the letters of the alphabets were numbered as A 26, B 25, C 24 and o on till Z 1.","QuestionTypeStructure":0,"OptionsList":[{"OptionValue":"5 ,12 ,4, 22, 15"},{"OptionValue":"6 ,12 ,5, 22, 15"},{"OptionValue":"5 ,14 ,4, 22, 16"},{"OptionValue":"4 ,13,4, 22, 12"}]}

    ]}

@model Test.UI.ViewModel.SurveyCollection
    @using System.Web.Script.Serialization

            [div style = "margin-bottom:10px"]

    [script type="text/html" id="0"]
        [div]
            [input type = "radio" style = "margin-right:10px; width: auto"/][span data-bind="text: $data.OptionValue" /]

        [/div]
    [/script]


        $(document).ready(function () {
            var surveyViewModel = {
                SurveyList: ko.observableArray([])
            };

            var data = $('').html("@(new JavaScriptSerializer().Serialize(Model))").text();
            var jsonData = $.parseJSON(data);
            if (jsonData != undefined) {
                //$.each(jsonData.SurveyList, function (baseIndex, T) {
                ko.utils.arrayForEach(jsonData.SurveyList, function (T) {
                    var surveyModel = new SurveyModel(T);
                    surveyViewModel.SurveyList.push(surveyModel);

                    ko.utils.arrayForEach(T.OptionsList, function (Q) {
                        var optionModel = new OptionModel(Q);
                        surveyModel.OptionsList.push(optionModel);
                        //surveyViewModel.SurveyList[baseIndex].OptionsList.push(optionModel);
                    });
                });
                ko.applyBindings(surveyViewModel);
           }
    });

    function SurveyModel(T)
    {
        this.QuestionNumber = ko.observable(T.QuestionNumber);
        this.Question = ko.observable(T.Question);
        this.QuestionTypeStructure = ko.observable(T.QuestionTypeStructure);
        this.OptionsList = ko.observableArray([]);
    }

    function OptionModel(Q)
    {
        this.OptionValue = ko.observable(Q.OptionValue);
    }

我为将html转换为其他内容而道歉 . 问题是上面的结果在mozilla的错误字段中表现为：

Error: Cannot find template with ID function observable() {
            if (arguments.length > 0) {
                // Write

                // Ignore writes if the value hasn't changed
                if ((!observable['equalityComparer']) || !observable['equalityComparer'](_latestValue, arguments[0])) {
                    observable.valueWillMutate();
                    _latestValue = arguments[0];
                    if (DEBUG) observable._latestValue = _latestValue;
                    observable.valueHasMutated();
                }
                return this; // Permits chained assignments
            }
            else {
                // Read
                ko.dependencyDetection.registerDependency(observable); // The caller only needs to be notified of changes if they did a "read" operation
                return _latestValue;
            }
        }
