data-presents old vs. new style

data-presents-example.js

// Given this HTML:
// <div data-presents='foobar'></div>

// Old style
// Usually written by passing org.casebook.views
// to an anonymous function as `ns`.
org.casebook.views('foobar', {
  initialize: function() {
    var el = this
  },
})

// New style
$(document).bind('foobar:present', function(event) {
  var el = event.target
})
