                setUnitLegend:"@",
            },  
    replace: true,
    template: "<div></div>",
    compile: function (tElem) {
    tElem.append(validElementScope);
    tElem.append(validElementTotal);    
        return link;
    }
  }
});

Here's the directive I'm trying to do: link

It uses angular.element : link

I need it to work exactly like this in pure javascript: link

javascript angularjs angularjs-directives angular-module

myApp = angular.module 'myApp', []

myController = ($scope) ->

    {key: 'property_01', value: 0}

  $scope.sum = ->
    s = 0
    _.map $scope.itens, (i) -> s += parseFloat("#{if i.value then i.value else 0}".replace(',', '.'))
    $scope.total = s

myApp.controller('myController', ['$scope', myController])
