group.id argument for draw listener

[yossidev]

In dwv/src/tools/draw.js

this.execute = function () {
       ...
        // callback
        this.onExecute({'type': 'draw-create', 'id': group.id});
    };

The group.id is Kinetic.Factory.addOverloadedGetterSetter.constructor.(anonymous function)

addOverloadedGetterSetter: function(constructor, attr) {
            var capitalizedAttr = Kinetic.Util._capitalize(attr),
                setter = SET + capitalizedAttr,
                getter = GET + capitalizedAttr;

            constructor.prototype[attr] = function() {
                // setting
                if (arguments.length) {
                    this[setter](arguments[0]);
                    return this;
                }
                // getting
                else {
                    return this[getter]();
                }
            };
        },

When I call this function from the listener 'this' is not the group.

Maybe, the code should be like the below

this.execute = function () {
       ...
        // callback
        this.onExecute({'type': 'draw-create', 'id': group.id()});
    };
