Using bootstrap.js from the deployment folder in a widget

Hi all,

I've just created a widget that makes use of a function in the bootstrap.js. Every Mendix project contains this file by default \deployment\web\lib\bootstrap\js but appearently I can't use functions in my widget. How can I access this file from my widget without adding the bootstrap.js and jQuery.js (since bootstrap.js requires it) to my widget. 

Thanks in advance!
