[jQuery] select parent node in context

[jQuery] select parent node in context


within a function for an onchange-handler ($(...).change(function(e)
{...) i tried something like:
$(":parent input[name^=subsequentProperty]", this);
this does not work, but:
$("input[name^=subsequentProperty]", this.parentNode);
does work.
what am i doing wrong? why doesnt the first example work?
