I have 2 values that I get from server A and B. I can only have one true at a time.
Again what I need is one of the radios to be checked at a time so one true value only.
var viewModel = {
radioSelectedOptionValue: ko.observable("false"),
A: ko.observable("false"),
B: ko.observable("false")
};
ko.applyBindings(viewModel);

<h3>Radio View model</h3>
<table>
<tr>
<td class="label">Radio buttons:</td>
<td>
<label><input name="Test" type="radio" value="True" data-bind="checked: A" />Alpha</label>
<label><input name="Test" type="radio" value="True" data-bind="checked: B" />Beta</label>
</td>
</tr>
</table>
A-<span data-bind="text: A"></span>
B-<span data-bind="text: B"></span>
