Reset checkbox

I have a scenario where a user has the ability to select a checkbox, however they are to get immediate feedback that it is the wrong answer and the checkbox should then be unchecked. I'm trying to use a free form checkbox for this, rather than a question and I cannot figure out how to get the checkbox to uncheck using an On Select/Change action. I've tried various "standard" JavaScript solutions, including the "click", the "checked" attribute change so far to no avail using RunJS. I even tried using JS that changed the variable itself.


Other than making it a "question" and forcing a reset of the question if they choose that particular checkbox, any thoughts on a way to force it to be unchecked after a user selects it?


Edit: It doesn't look like I can find a "reset question" option either, so still stumped how I would be able to do this at all.


Cheers,
