I created a simple view to test it, and in my situation, it works:
Code:
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
</head>
<body>
<h1>Test button</h1>
<div>
<button id="myCamp" class="btn pull-right btn-danger navbar-btn">Active Campaign: None</button>
</div>
<br />
<div>
<button class="make-active">Set My Campaign</button>
</div>
<script>
$(document).ready(function(){
$('.make-active').click(function(e){
e.preventDefault();
alert('You clicked on a button with the css class make-active.');
});
});
</script>
</body>
</html>
