Handlebars.registerHelper('eachkeys',function(context,options) {
  var fn = options.fn,inverse = options.inverse;
  var ret = "";

  var empty = true;
  for (key in context) { empty = false; break; }

  if (!empty) {
    for (key in context) {
        ret = ret + fn({ 'key': key,'value': context[key]});
    }
  } else {
    ret = inverse(this);
  }
  return ret;
});

$(function() {
    var data = {"interval":"2012-01-21","revenue_type":"CPA"};
                
    var source   = $("#template").html();
    var template = Handlebars.compile(sourcE);
    $('#content').html(template({'data': data}));
