I have this field that I'm trying to clear:

But it won't clear (the radio button clears perfectly ... and hides):

$(document).ready(function(){
//set fields to read only
  $('#Field91-1').attr('checked', false); //Clear NO Radio Button
  $('.wccAction').hide(); //Hide WCC Action field
  $('.wccComments input').val(""); //Clear WCC rejection comments field
//  $('.wccComments').hide(); //Hide WCC rejection comments field
});  //close document.ready

I already tried:

$('.wccComments input').val("").change(); //Clear WCC rejection comments field

Any other suggestions?
