Uncheck a checkbox - Interaction Help


So, I want like a basic interaction and I am not able to do it.

I want a check box to be unchecked when I click on a button on a page.
So need to add an trigger for the button (Clear ALL) that effects the check box on the page. How would I go about changing the value (check or uncheck) for the checkbox.

The only properties I could trigger seems like Hide/Show or any visual changes. How do I change the property of checkbox through animations/interactions ?
