ui tabs - js calls on ajax loaded page

ui tabs - js calls on ajax loaded page

I have ui tabs set up to load content via ajax
<li><a href="myPage.cfm""><span>My Page</span></a></li>


I think the issue is that the flexigrid plugin is loaded on the calling page and the ajax loaded page can not access it.
Getting the following JS error
    $(".flexigrid").flexigrid is not a function

Does the called page need to be a full HTML page (with own js to load plugin)?
Or can it be just the HTML Table

Which page should have the plugin call?
    $('.flexigrid').flexigrid()


Thank you.
