Jquery KendoMobile MVVM kendo.observate，从JSON获取数据

我对如何从serwer json中检索数据有疑问。 我最初的想法是以MusicStore为例，帮助自己检索数据，我被卡住了

看法

正在检索数据

define(["jQuery", "kendo", "config", "utils"], function ($, kendo, config, utils) {

    var _wcfSchemaData = function (data) {
        return data.Data;
    },

         _wcfSchemaTotal = function (data) {
             return data.Count;
         };

    var DataSourceConfig = function (url, sortField, options, dataType) {
        this.transport = {
            dataType: dataType,
            read: url
        };
        //this.sort = {
        //    field: sortField,
        //    dir: "asc"
        //};
        //$.extend(this, options || {});
    };

    DataSourceConfig.prototype = {
        //type: "json",
        schema: {
            data: _wcfSchemaData,
            total: _wcfSchemaTotal
        },
        requestStart: function () { if (this.pageSize() === undefined || this.page() === 1) { utils.showLoading(); } }, //infinite scrolling has its own, less obtrusive indicator
        requestEnd: function () { utils.hideLoading(); },
        error: function () { utils.hideLoading(); utils.showError("There was an error loading the data from the server. Please close the app and try again."); }
    };

    //var EndlessScrollDataSource = kendo.data.DataSource.extend({
    //    _observe: function (data) {
    //        if (this._page > 1) {
    //            this._data.push.apply(this._data, data);
    //            return this._data;
    //        }
    //        return kendo.data.DataSource.prototype._observe.call(this, data);
    //    }
    //});

    return {
        clear: function (dataSource) {
            dataSource.view().splice(0, dataSource.view().length);
        },

        expositionsList: new kendo.data.DataSource(new DataSourceConfig(config.expositionUrl + "?lang=pl-PL", "Name",null,'json')),

    };

});

我得到了一个错误。。。未捕获的TypeError:对象[Object Object]没有方法“调用”

我怎样才能解决这个问题，让它发挥作用 Jsonson在这里

Tx寻求帮助

这方面运气好吗，Andrzej？我正试着做同样的事情。我的DataSourceConfig调用发生了，但它从未实际调用该服务。是的，我有完整的解决方案，我将在短时间内共享。@Andrzej Do share，我正在研究相同的问题。

define(["jQuery", "kendo", "data", "utils"], function ($, kendo, data, utils) {
    return {
        onShow: function (e) {
            utils.log("expositions-view: onShow: " + e)
        },

        viewModel: kendo.observable({
            expositions: data.expositionsList
        })
    };
});

define(["jQuery", "kendo", "config", "utils"], function ($, kendo, config, utils) {

    var _wcfSchemaData = function (data) {

         _wcfSchemaTotal = function (data) {
             return data.Count;
         };

    var DataSourceConfig = function (url, sortField, options, dataType) {
        this.transport = {
            dataType: dataType,

        };
        //this.sort = {
        //    field: sortField,

    return {
        clear: function (dataSource) {
            dataSource.view().splice(0, dataSource.view().length);
        },

        expositionsList: new kendo.data.DataSource(new DataSourceConfig(config.expositionUrl + "?lang=pl-PL", "Name",null,'json')),

    };
