Added an event to listen too after json loaded

[jcphlux]

I added a trigger to the getJSON so I could listen to the event.

Changes -
request = $.getJSON(settings.url, data, function(json) {
build.call(self, json);
/* Force updating the children. */
$(self).trigger("change");
$(self).trigger("dataLoaded", [self]);
});

Usage -
$("target_select").on("dataLoaded", function (e) {
//do stuff.
});

I also need this but the event name should be namespaced to avoid collisions with other libraries. Maybe the event should be named load.chained.remote.

Will try to prepare a PR.

Well, I've forked the project, made the change, created a test and... works ok with jQuery, fails miserably with Zepto.

Seems that the problem is on the event name.

If I use load.chained.remote as the event name it works only with jQuery.
If i use customloadevent as the event name it works everywhere.

I am far from being an expert, so googling about this I found a related article with helpful comments. I'm sending the PR with the event named as chaned:load but suggestions are very welcome.

that feature should be integrated into the project
