[jQuery] $.ajax({datatype:"html"... does not seem to evaluate scripts?

[jQuery] $.ajax({datatype:"html"... does not seem to evaluate scripts?


The documentation notes that when using the $.ajax() functions option
datatype="html":
"html": Returns HTML as plain text; included script tags are
evaluated
however, it does not appear to me that this is happening. What am I
missing?
My very simple code is here:
-----------------
...

$.ajax({type:"GET",dataType:"html",url:"test.htm",success:function(dta)
{
alert(dta);
}});
...
----------------
----test.htm--
<div>hello</div>
<script language="JavaScript">
alert("hello?");
</script>
--------------
I do get my alert with the content from alert(dta), but I never get an
alert with "hello?". What am I missing?
