If i understand correctly, u wand to know wheter the input value exist in binded values. For this case i use the follow js:

cmbChangeWorkType: function () {
    var combobox = $('#WorkTypeId').data('kendoComboBox');
    var ds = combobox.dataSource;
    var value = combobox.value();
    var data = ds['_data'];
    var item = pdInfo.getByGuid(data, value);
    if (item == null) { // check wheter the input value exist in binded values
        combobox.value(null); // set the null if value not in list
    }
},

getByGuid: function (data, guid) {
    for (var i = 0; i < data.length; i++) {
        if (data[i]['Guid'] == guid) {
            return data[i];
        }
    }
    return null;
},
