.trigger.click button(div) in parent window without ad-block issues, HOW?

I want a button in my Iframe to click a button in its parent window.
I got this to work with a few lines of code, but the adblocker blocked that code in some browsers, now I am looking for an alternative.

I was thinking about something like this:

the button in the iframe:

Symbol.bindElementAction(compId,symbolName,"${ _Rectangle }","click",function(sym,e){
window.parent. functionid ();
});


the script in the parent page:

<script>
$(document).ready(function functionid (){
    $( '#u181' ).trigger('click');
});
</script>


This script does >not< work, does anyone know why? or does anyone have an alternative?
Thanks in advance.
