Hi,
I think that the reason why yo do not get your event trigerd is that
you haven't told `require` that IPython.events needs to be defined
before you are called. You need to use something along the lines of
teh following
define(['base/js/namespace'], function(IPython){
// your code, will be run only once base/js/namespace is loaded and
with IPython == value return by base/js/namespace executed.
// ...
})
It's far from being easy to understand how these things work, but that
should put you on the right track.
