MVC :: Client Scripts Not Running After Async Postback?

I have a MVC view, say,:

[Code]....

somepartialview calls other partial views, that also contains client javascript. This loads and works fine, the javascript-based effects (vertical ticker, horizontal ticker) work fine as well.

The problem is that somepartialview has several AJAX.ActionLink(s) like this:

Ajax.ActionLink("LinkText", "SetIcons", new { id = l.ID }, new AjaxOptions { UpdateTargetId = "ajaxdiv" })
Namely, an <a> element which upon click changes the content of <div id="ajaxdiv"> using a 'SetIcons' controller:

[Code]....

But this works only partially: the page gets refreshed with the new HTML content, but the scripts that worked before the async postback do not run anymore. How do I get them to work?

I think that I am looking for the MVC alternative of the WebForms' ScriptManager.RegisterStartupScript

OSDBDataContext db = new OSDBDataContext();
