not too sure if I understand your question exactly .. are you looking for examples on how to use events with jquery.json2html? or how to pass an object to keep context using eventData?
In either case here's a simple example that does both:
var data = [{'name':'click me'}];
var transform = {'tag':'button','html':'${name}','onclick':function(e){console.log(e.data);}};
$('#buttons').json2html(data,transform,{'eventData':'some data object'});
