// possible fix for http://github.com/jquery/jquery-datalink/issues/#issue/2

// added
var _oldval = $.fn.val;
$.fn.val = function(value) { 
  var result = null;
  if (value == undefined) {
    result = _oldval.call(this);
  }
  else {
    result = _oldval.call(this, [value]);
    $(this).trigger('change', ["name", value]);
  }
  return result;
};

// changed
function setValue(target, field, value) {
  if ( target.nodeType ) {
    var setter = fnSetters[ field ] || "attr";
    $(target)[setter](value);
  } else {
    // $(target).data( field, value );
    target[field] = value;
  }
