Creating $("<select>", { attribute object }) isn't recognizing the attribute object

Creating $("<select>", { attribute object }) isn't recognizing the attribute object

 
$(document).ready(function() {
    var mselector = $("<select></select>",  {
          'alt': 'ROLLOVER TEXT',
          'multiple': 'multiple',
          'click': function() {
              alert('in click');
                  return false;
              }
    });
    mselector.appendTo('body');
 });










The SELECTor shows up in the document but it's not MULTIPLE, no ALT text, no CLICK event handler.
What am I missing?
