CheckboxGroupView - check all

Hello,

I'm currently working with the splunk web framework in v6 and I'm using the CheckboxGroupView. I'd like to know if there is a way to check all checkboxes a the same time with this object.

So far I can use a javascript to do a check all as below, but the CheckboxGroupView object isn't refreshed (we can see that it is ticked, but the object underneath isn't set accordingly):

$(':checkbox').each(function() {
    this.checked = $that.is(':checked');
});

Do you know if there is another way to do a tick all? or a way to refresh CheckboxGroupView object?

Regards, Olivier
