Help needed about remove and cancelSelection

[petrospap]

Hello
First of all thanks for this very useful script.
I need a help from you guys, my knowledge is not very good when it comes to javascript/jquery
I have a page where I load an external file with $ajax, in this file I load another file where I call lot of images with imgAreaSelect
i.e

$('#thump1').imgAreaSelect({ aspectRatio: '4:3',  onSelectChange: myfunction });
$('#thump2').imgAreaSelect({ aspectRatio: '4:3',  onSelectChange: myfunction });

is working as expected, but I have problem to remove imgAreaSelect with a click a button from the FIRST PAGE
what is works (but I got problems also) is something like this

$(document).on('click', '.button', function(){
var ias = $('#thumb1').imgAreaSelect({instance:true});
    if (ias){
       ias.cancelSelection();
       ias.remove();
    };
});

cancelSelection works, remove is NOT working
so if call cancelSelection in 2-3 images I got lot of hidden imgareaselect-outer divs
I use jquery.imgareaselect.dev.js
Can you please help me out here?
