beforeinsert / beforechildinsert cq:listener does not fire up

Hi!

I have the following cq:editConfig file:

<?xml version="1.0" encoding="UTF-8"?><jcr:root xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"    jcr:primaryType="cq:EditConfig"><cq:listeners        jcr:primaryType="cq:EditListenersConfig"        afteredit="REFRESH_PAGE"        beforeinsert="function (){ return OrderModule.prototype.checkCountBeforeAdd(); }"        beforedelete="function (){ return OrderModule.prototype.checkCountBeforeRemove(); }"            /></jcr:root>

'beforedelete' event is fired up ok, but 'beforeinsert' doesn't not fire up, 'beforechildinsert' neither.

Could you please direct me to the correct direction?

Thank you in advance.
