Kendo grid custom editor dropdownlist / combobox populates with [object.object]

A side note: Where does one post something just so people can google it in future?

So when trying to populate a field in a kendo grid using a custom editor with a kendo combobox or similar, the editor dorpdown works fine but as soon as you leave the editor (leave the field) it populates the input with [Object.object]. This is following the kendo example to the letter!

In this question I will post the code from the kendo page Configuration, methods and events of Kendo UI Grid[^]

What I have tried:

JavaScript

$("#grid").kendoGrid({
  columns: [ {
    field: "name",
    editor: function(container, options) {
     // create an input element
     var input = $("<input/>");
     // set its name to the field to which the column is bound ('name' in this case)
     input.attr("name", options.field);
     // append it to the container
     input.appendTo(container);
     // initialize a Kendo UI AutoComplete
     input.kendoAutoComplete({
       dataTextField: "name",
       dataSource: [
         { name: "Jane Doe" },
         { name: "John Doe" }
       ]
     });
    }
  } ],
  editable: true,
  dataSource: [ { name: "Jane Doe" }, { name: "John Doe" } ]
});

The solution is to ignore that example and use the example they have for validation. Simply adding a couple of extra attributes solves the issue (I have no idea why)

JavaScript

editor: function (container, options) {
	// create an input element
	var input = $("<input required data_value_primitive = 'true' />");
	// set its name to the field to which the column is bound ('name' in this case)
	input.attr("name", options.field);
	// append it to the container
	input.appendTo(container);
	input.kendoComboBox({
		autoBind: false,
		suggest: true,
		dataSource: ["Sole Trader", "Partnership", "Ltd", "LLP", "Plc", "Charity", "Public Sector", "Club/Society"]
	});

}

I was my colleague who had this issue. He really didn't want to post anything because he's still pretty angry :Þ

If anyone has a better solution, or can explain this one then I'd really appreciate it.

As stated in the question. This post is just for posterity ^_^
