Actions fail for 'radio' type if there are 2 or less values

[kyork-cl]

To reproduce, create a device with an action that has a 'radio' type parameter with two or less values

.map('SetMode', this.SetMode, [{name:"mode", type:'radio', value:[{value:'Off'},{value:'Auto'}]}])

And open the server in the browser. You'll see there are two buttons instead of a drop down selector. When the button is pressed, a POST is generated, but no form data is included for the action.
