Javascript error on minified version

[jjelosua]

Hi, I am checking out the timeline-setter tool and doing some tests with the demo csv file I was able to generate the timeline, but using the same data and generating it with the minified option it gives me a javascript error and the series checkboxes disappear.

timeline.html:36 Uncaught TypeError: Cannot read property 'preventDefault' of undefined
timeline.html:36 _.extend.showNotches
timeline.html:5 b.speed.r.complete
timeline.html:3 b.Callbacks.c
timeline.html:3 b.Callbacks.p.fireWith
