filter _.any() function doesn't work underscore.js

Question

I have a problem with collection functions filter_.any() from underscore.js. the part of code with filter() will never execute. I can't understand why? I took this code from this example http://blog.pixelingene.com/demos/d3_tree_clipPath/ and I included the same underscore-min.js library into my project but it didn't help to resolve my problem

can someone please help me how to resolve this issue? or may be some alternative way ? Thanks

function setupMouseEvents()
