The pushbutton is not pressed in the mobile versions, how to fix?

In General, the problem is
there is a website avtoklondaik.ru joomla 3.5
To the right is a menu, it works fine in the normal version of the site, but when you come from a mobile, do not press the "menu" button or is pressed and does not respond...
And when simply changing the screen size in the browser is not want from a mobile device
What could be the problem?

Because there is adaptation just using media quires

PS
code display menu
<script type="text/rocketscript" data-rocketoptimized="true">jQuery(document).ready(function($){$("#btn-menu#close-on").click(function(){if($('#wrap-mainmenu').hasClass('selected')){$('#wrap-mainmenu').removeClass('selected');}else{$('#wrap-mainmenu').addClass('selected');}});$(function(){$('ul.nav li.deeper').hover(function(){$submenuHeight=$(this).find('ul.nav-child').height();$('#wrap-mainmenu').css('padding-bottom',$submenuHeight+50);},function(){$('#wrap-mainmenu').css('padding-bottom',0);});});});</script>


the menu itself
<div id="btn-menu" class="visible-lg-block visible-md-block visible-sm-block visible-xs-block col-lg-2 col-lg-reset col-md-3 col-md-reset col-sm-3 col-sm-reset col-xs-3 col-xs-reset"><div class="custom"><p>Menu</p></div></div>

Link tried, also does not want to work

<script type="text/rocketscript" data-rocketoptimized="true">
jQuery(document).ready(function($)
{
$("#btn-menu, #close-on").click(function()
{if($('#wrap-mainmenu').hasClass('selected'))
{$('#wrap-mainmenu').removeClass('selected');}
else
{
$('#wrap-mainmenu').addClass('selected');}
}
);
$(function(){
$('ul.nav li.deeper').hover(function(){
$submenuHeight=$(this).find('ul.nav-child').height();
$('#wrap-mainmenu').css('padding-bottom',$submenuHeight+50);},
function(){$('#wrap-mainmenu').css('padding-bottom',0)
;})
;});}
);</script>
