Description
- create a function xxx
- inject some html with name=xxx [I'm using <form> but not sure if it's specific got <form> only]
function xxx works 1st time only. 2nd time I get a javascript error - xxx is not a function.
Both IE & FF have the problem, both IE & Firebug debuggers can see the original function and execute it.
sample code that reproduces it is here. if i rename the function tester() to another name it works. The 2nd click should give you the 'undefined function' error.
<html> <head> <script src="/admin/js/jquery.js" type="text/javascript"></script> <script> var seq = 0; function tester() {
seq++; $('#tester')[0].innerHTML = "<form name='tester'>I've been clicked ".concat(seq," time(s)</form>");
} </script> </head> <body>
<div id='tester'>tester div here</div> <a href='#' onclick='tester();return false'>click me 2 times</a>
</body> </html>

You have a name conflict, this is independent of jQuery.

Also I know it's just a demo but:
$('#tester')[0].innerHTML = ...
This will cause memory leaks if #tester has jQuery data or events.
onclick= ...
Inline event handlers are a bad idea. http://docs.jquery.com/Won't_Fix#Inline_Event_Handlers
