JS error thrown when using a RadioButton in Grid's custom popup template

[IvanDanchev]

Bug report

Reproduction of the problem

1. Set up a Grid for popup editing:

.ToolBar(toolbar => toolbar.Create())
.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("RadioButtonTemplate"))

Add a RadioButton in the RadioButtonTemplate.cshtml template:

@model GridExample.Models.OrderViewModel

@(Html.Kendo().RadioButton().Name("engine1").Checked(true).HtmlAttributes(new { @name = "engine" }).Label("1.4 Petrol, 92kW"))
@(Html.Kendo().RadioButton().Name("engine2").HtmlAttributes(new { @name = "engine" }).Label("1.8 Petrol, 118kW"))

2. Click the "Add new record" button in the Grid's toolbar.

Current behavior

A js exception is thrown and the popup does not open:

Chrome:
Uncaught TypeError: Cannot read properties of undefined (reading 'toString') kendo.all.js:313050

Firefox:
Uncaught TypeError: this.bindings.checked.get() is undefined kendo.all.min.js:10:102181

The issue is reproducible with a RadioButton or a RadioButtonFor helper.

Expected/desired behavior

No exception is thrown and the custom popup displays the RadioButton.
