KendoComboBox仅绑定值，而不是预先填充的某些字段的文本

Question

我目前正在将kendo组合框与json设施集（DMIS）绑定。有一个COMBINED字段，其中包含要绑定的设施的ID和标题。但是，只有ID会显示在框的预填充中。从组合框中选择其他设施时，一切都会显示出来。只是初始填充仅显示该ID，而应同时显示ID和TITLE。知道为什么它只显示ID以及如何在预填充时正确绑定ID吗？

    //ask a question dialog popup
    $("#askdialog").kendoDialog({
        open: function () {
            $("#facility").kendoComboBox({
                dataTextField: "Combined",
                dataValueField: "DMISID",
                filter: "contains",

                    transport: {
                        read: function (options) {
                            console.log(options);
                            if (typeof options.data.filter != "undefined" && options.data.filter != null &&
                                typeof options.data.filter.filters != "undefined" && options.data.filter.filters != null && options.data.filter.filters.length > 0) {
                                var DMIS_NAME = options.data.filter.filters[0].value;
