How to call a javascript function after an async postback

Question

I was using the following script to call a javascript function only if my page in Edit Mode:

protected void Page_PreRender(object sender, EventArgs e)
{
    if (EditMode)
        ClientScript.RegisterStartupScript("".GetType(), 
                                           "EnableSelectableKey", 
                                           "EnableSelectableForRolesLists();",
                                            true);
}

After I added an update panel, the script has not been called.

How to fix the problem?

Using Sys.WebForms.PageRequestManager.endRequest as Dave_Stott says is a cleaner way to do this (if there is such a thing as "clean" when talking about UpdatePanels and client/server interaction). But you can also simply change your code to use ScriptManager instead of ClientScript and it should work:

ScriptManager.RegisterStartupScript("".GetType(), 
                                           "EnableSelectableKey", 
                                           "EnableSelectableForRolesLists();",
                                            true);

I'm sorry, but that link has nothing to do with the question.

Pretty sure it does. See the answer by Jamie Treworgy which also references the exact same technique as a possible solution and provides an alternative. Answer is also accepted...
