Changing Checkbox and Radio Buttons from Javascript.

Changing Checkbox and Radio Buttons from Javascript.

I have a form that I want to populate based on which 'line' of data I am on.  The form as a couple of checkboxes in it.

I know that I can find the various UI pieces that need to be changed and add/change classes.  But this requires that my code be aware of some of the inner workings of Mobile.

I was hoping that there would be a way to "trigger an event" (maybe?) that tells Mobile..
"Hey.. I changed the state of this checkbox/radiobutton.. make yourself look that way".

I tried
$("#checkhere").checked=false;
$("#checkhere").trigger("change");

but that didn't seem to make any difference.
