If we have some "select" elements which are used the "live" binding model:

$("select").live("change", fn);

and some "select" elements which are used the "inline" binding model:

<select onchange="fn();">...</select>

and if we call the "change" event then this event will be called twice.

If we re-write the existing "inline" binding model to the the following binding model:

$("select").change(fn);

then this case will not reproduced.

Please, see the attached example.

Note: Reproduced only in IE 8 (IE 7 compatibility mode)
