Bootstrap3 navbar doesn't close - html

Question

I have an issue where the Bootstrap 3 navbar when it is converted into a dropdown menu on small devices (see code below). The issue is that once a menu link has been selected, the navbar dropdown doesn't close.
Any pointers where to start looking greatly appreciated.
<nav id="y-navbar" class="navbar navbar-default navbar-fixed-top" role="navigation">
<div class="container">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#"><img class="y-logo" src="images/template-logo.png" alt="logo"/></a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li class="active"><a class="y-nav-link" data-partial="home.html" href="#"><i class="fa fa-home"></i> Home</a></li>
<li><a id="y-nav-about" class="y-nav-link" data-partial="about.html" href="#">About</a></li>
<li><a class="y-nav-link" data-partial="contact-us.html" href="#">Contact</a></li>
<li><a class="y-nav-link" data-partial="map.html" href="#">Directions</a></li>
<!-- Page Layouts -->
<li class="dropdown">
Layouts <span class="caret"></span>
<ul class="dropdown-menu" role="menu">
<li><a class="y-nav-link" data-partial="feature-boxes.html" href="#"><i class="fa fa-file-code-o"></i> Feature Boxes</a></li>
<li><a class="y-nav-link" data-partial="four-blocks.html" href="#"><i class="fa fa-file-code-o"></i> Four Blocks</a></li>
</ul>
</li>
</ul>
</div>
</div>
</nav>

You can add in a script to let the menu close after click:
$(document).on('click','.navbar-collapse.in',function(e) {
if( $(e.target).is('a') ) {
$(this).collapse('hide');
}
});
