How to add this element in runtime ?

Hello,

I need a small help to catch an element and add another element in run-time using jQuery.
The HTML looks like this -

<td class="fieldCell"><input class="inputbox" id="password" type="password"><span class="cbFieldIcons">lots of HTML codes</span>....</td>



I want to add some more element in .... place. That is, just after the <span class="cbFieldIcons"> ends.
Please note that there is actually no .... in actual code.

I personally wrote a code using jQuery, but some reason, it is not working in IE6 and IE7.
