Use Twitter Bootstrap button group as radio select with knockout bindings

Question

This is working:

view.html

<div><input type="radio" name="radioPriority" data-bind="checked: priority" value="want" style="margin-top: -3px; margin-right: 3px;" />I want to</div>
<div><input type="radio" name="radioPriority" data-bind="checked: priority" value="need"  style="margin-top: -3px; margin-right: 3px;"/>I need to</div>

controller.js

function feedbackViewModel() {
    var self = this;
    self.priority = ko.observable("want");
    //lots of other stuff
}

As expected, when you select the second radio the priority observable's value changes to "need". However, I'd like to use a Twitter Bootstrap button group as a radio. Here is the HTML I have, but it does not change the observable as expected:

<span class="btn-group" data-toggle="buttons-radio">
    <button data-bind="checked: priority" type="button" class="btn" value="want">I want to</button>
    <button data-bind="checked: priority" type="button" class="btn" value="need">I need to</button>
</span>

update I have a jsfiddle going here: http://jsfiddle.net/a8wa8/6/ "priority1" is the standard radio selects and "priority2" is the bootstrap buttons.

The issue is that you are using Checked binding with button which is not allowed, instead you can use click binding. check this fiddle:

Yes you can achieve this by using ko css binding. Check this updated fiddle:
