$().attr does not work popperly with type

[Licenser]

When creating a new html element via $() using .attr() to set the type of the input causes a expection that type can't be changed.

var checkbox = $('<input/>');
checkbox.attr('type', 'checkbox'); // => exception

a workaround is:

var checkbox = $('<input type="checkbox"/>');

The fix for this will probably appear in jQuery.clean(). Once appending the HTML string to that temporary div, parentNode will no longer return undefined and the throw will be executed:

if ( name == "type" && jQuery.nodeName( elem, "input" ) && elem.parentNode ) {
    throw "type property can't be changed";

Test Case

[flesler]

For some reason it makes a test fail.. but seems like a feasible solution

[flesler]

Alternate solution, no test fail, don't ask why!!!
