javascript - Backbone Marionette Disable and Enable events using Wreqr

Question

I'm using Backbone Marionette and exploiting it's Event Aggregator. I'm kinda stuck in this scenario wherein I can't trigger the previously offed event (using .off()).

Consider the code sample below:

vent.on('generateStat');
vent.off('generateStat');
vent.on('generateStat'); // Non trigger-able anymore

How can I do this? On second thought, what's a better way to do this?
