How to change the radio button selection using funcUnit

I am trying to change the radio button selection using funcUnit.
To change the radio button selection I try to select the radio button element (which is not selected) and then generate a click event on the radio button to change the selection but its not working.
I am not sure if it the correct way of changing the selection of radio button in funcUnit.

Are you using F(selector).click()?

Please check the following example:

Yes, I was using F(selector).click() to change the selection

Could you please try the example I’ve shared.
Do you have anything different?
If possible please share an example?
