JQuery accordion - unbind click event

JQuery accordion - unbind click event

I am writing a form wizard using JQuery's accordion module. The
problem is I want to override any mouse clicks on the accordion menu
so that the form is validated first before the accordion will show the
next section.
I have tried the following:
$('#accordion h3').unbind();
$('#accordion h3').click(function() {
if (validate())
{
$("#accordion").accordion('activate', 2);
}else
{
alert("invalid form");
}
}
But the above code doesn't work. The built-in click event of the
accordion still gets called and the accordion shows the next section
regardless of whether the form is valid or not.
I have also tried the following code:
$('#accordion h3').click(function(event) {
if (validate())
{
$("#accordion").accordion('activate', 2);
}else
{
alert("invalid form");
}
event.stopPropagation();
});
But the stopPropagation() call doesn't seem to affect the accordion
behaviour at all, the next section is displayed whether or not the
form is valid.
Any idea what I may be doing wrong?
Thanks!
