Radio Button List with Knockout.js

Question

I'm trying to build a list of radio buttons with labels so that you can click the label to check the radio item. What I have works fine in Chrome, but not IE7. The HTML that get's spit out seems like it is correct, but when I click on the label, the corresponding radio button doesn't get selected.

JavaScript

function ReuqestType(id, name, billable) {
    this.id = id;
    this.name = name;
    this.billable = billable;
}

function RequestViewModel() {
    var self = this;

    self.availableRequestTypes = [
        new ReuqestType(1, "Travel", true),
        new ReuqestType(2, "Bill Only", false),
        new ReuqestType(3, "Both", true)
    ];

    self.selectedRequestType = ko.observable();
}

HTML

Request Type
<br />
<!-- ko foreach: availableRequestTypes -->
<input type="radio" name="requestType" data-bind="value:id, attr: {'id': 'rt'+ id}" />
<label data-bind="text: name, attr:{'for':'rt'+id}">
</label>
<!-- /ko -->

What is the preferred way to do this?

Answer 1

This seems to be working correctly now as of the newest version of Knockout (2.1.0).
