    You could remove the onchange attribute and register a startup script that will fire after the postback has completed which i think in effect will work just as you want.

    In your OnSelectedIndexChanged Event you can use.

     Page.ClientScript.RegisterStartupScript(this.GetType(), "testScript", "markItUpApply();", true);

    EDIT:

    In case you have update panel in the page then use this code

    ScriptManager.RegisterStartupScript(this, GetType(), "testScript", "markItUpApply();", true);

    hope this helps.
