[jQuery] Hmm... Got stuck at 1 point.

[Fastforward]

I got one question mark over my head and I please someone for little
help.

I have this

        $j.ajax({
          type: "POST",
          url: domain+"pages/groups/add/about",
          data: "action=start",
          error: function(msg){
                        $j("#progress").addClass("progress-error");
                        $j("#progress #pmessage").text("Ops! There was error 
with
loading... Please report problem!");
          },
          success: function(content){
            $j("#tabs").append(content);
            $j("#progress #pmessage").text("Loaded... ");
            setTimeout('$j("#progress").fadeOut("slow");', 2000);
          }
        });

And when this method is executed, content response normally. Problem
is when I'm trying to do some effects when user is working with
returned content.
For example

$j("#type").bind("click", function(){

    var typevalue = $j("#type").attr("value");

    if ( typevalue == "standalone" )
    {
           $j("#parent").attr("disabled", "disabled");

    }else if ( typevalue == "parent" )
    {
           $j("#parent").attr("disabled", "");
    }
});

This is located in base file inside of head element where rest of
scripts are too but this doesn't response at all.

If for example i set this function inside of returned file than
everything works normally.

Is there any possible way to do it w/o setting up script tag where is
returning content?

Thanks a lot!
