mobile menu disappear in internal pages

I install the CK menu with the mobile plugin.
Can be seen in www.yairl.com/eby (it is in Hebrew)

I had several issues BUT the problematic one is the use the menu in internal pages (sub-menu).

When clicking on one of the internal items in the menu on the new page the menu icon disappear. I tried to investigate it and saw that the part of the 'icon code' does not exist in internal pages...

Hi
there is no maximenu module in this page, or not with the "default" layout

Thanks for the quick response...
BUT how can I see (view source) the menu items...
And if I inspect element and search for 'menuck' I can find it as you can see bellow

I check this page
www.yairl.com/eby

and by my side your code is not present
are you sure that it is public and for this language, on this page ? Please check

you must check it on mobile device (or use 'user-agent' changer)
I am using two different template (mobile and normal)

ok I see now
you have an error with

$(window).addEvent('domready', function(){
$$('p.jf-copy').setStyle('display', 'none');
})

you must fix this, because it breaks the other scripts
