Jquery Mobile, Collapsible set and childrens - jquery-mobile

Question

I'm trying to populate the content of JQM accordions/collapsible sets dynamically. I've had a look at http://the-jquerymobile-tutorial.org/jquery-mobile-tutorial-CH20.php, but the examples seem to be outdated. So I've tried to come up with a working example, but I'm currently stuck and can't see, why this shouldn't work:
<script type="text/javascript">
$(document).ready(function() {
$(".mySet").bind('expand', function (event, ui) {
/* This prints e.g. "This is the first entry\n
I'm the collapsible set content for section 1." */
console.log($(this).text());
/* This should print "This is the first entry" (=the innerText of <h3>)
but it doesn't, it prints "This is the first entry\n
I'm the collapsible set content for section 1." as well */
console.log($(this).next().text());
/* This should just print "I'm the collapsible set content for section 1"
(=the innerText of <p>) but it doesn't, it prints e.g. "This is the
first entry\n I'm the collapsible set content for section 1." as well */
console.log($(this).nextAll("p").text());
});
});
</script>
<div data-role="collapsible-set">
<div data-role="collapsible" class="mySet">
<h3>This is the first entry</h3>
<p>I'm the collapsible set content for section 1.</p>
</div>
<div data-role="collapsible" class="mySet">
<h3>This is the second entry</h3>
<p>I'm the collapsible set content for section 2.</p>
</div>
</div>
Does anyone see, why jQuery won't descend on $(this) (=which points to the currently expanded <div ...class="mySet">? If I debug this code in Opera's DragonFly I can see, that $(this) seems to be the same as $(this).next() (at least they have the same values for innerHTML etc.)
Thanks for your help!

So, after fiddling around a little bit I came up with the following hack/workaround:
$(document).ready(function() {
$(".mySet").bind('expand', function (event, ui) {
/* I'm just creating a new var "myDiv" which points to my current div (so in a
way "myDiv" is just a copy of "this" */
var myDiv = $("#"+$(this).attr('id'));
var myP = myDiv.find('p:first');
// Works as expected, prints "I'm the collapsible set content for section 1."
console.log(myP.text());
});
});
