How to stop Senna.js from calling multiple jQuery event handlers

I have developed a SPA website using Senna.js and it works great! However, I have recently noticed that it doesn't remove jQuery event handlers when leaving the page. So I have all kinds of functions firing twice when I navigate back to a page I have already visited.

I fixed most of my personal code by doing this

$("#element").off("event").on("event", etc.)

But there are thousands of lines of other people's code which is also powering my website and I am worried that they are firing twice as well.

Does anybody on SO have any insight or approaches to handling this?

You can detach event handlers using Senna's lifecycle events. For example: 

var app = new senna.App();

app.on('beforeNavigate', function() {
// detach jQuery event handlers
});
