Get multiple checkbox data attribute

How I can get multiple checkbox data-attribute (only checked)?

I can get checkbox values, but not data attribute:

<script type="text/javascript">
//export upc
  $('#export_upc').click(function(){
    var arr = $('.checkboxes:checked').map(function(){
        return this.value;
    }).get();
    console.log(arr);
}); 
</script>

I tried return this.data("upc"), but this is not working.
