Angular JS + Kinetic = dynamic chart on canvas

here is the fiddle: http://jsfiddle.net/paska27/L6VAe/5/

the code (so complains otherwise):

<div ng-app ng-controller="MainCtrl"
ng-init="list = [
{name: 'Sergey', age: 26},
{name: 'Johan', age: 27},
{name: 'Iwan', age: 28}
];">
    <div id="box" ng-controller="PlaneCtrl"></div>       
    <input ng-model="currentItem.name" />
</div>

/** an extention of Kinetic shape (group, rect or what ever) **/
var Item = function(planeScope, item){
Kinetic.Group.call(this, {
    draggable: true
});

var self = this;

var text = new Kinetic.Text({
    x: 0,
    y: 0,
    text: item.name,
    fontSize: 20,
    fontFamily: 'Calibri',
    textFill: 'green',
    draggable: true
});

self.add(text);

self.name = text.getText();

self.on('dragstart', function(){
   planeScope.$parent.currentItem = self;
   planeScope.$apply();       
});
}
Kinetic.Global.extend(Item, Kinetic.Group);

var MainCtrl = function($scope){
    $scope.currentItem;
}

var PlaneCtrl = function($scope, $element){
    var stage = new Kinetic.Stage({
    container: 'box',
    width: 200,
    height: 200
}),
layer = new Kinetic.Layer();

angular.forEach($scope.list, function(item){
    item = new Item($scope, item);
    layer.add(item);
});

stage.add(layer);   
}

The task:

• i need to build some kind of a chart with items on it (just items, to keep it simple here)
• items could be any shape in the future (actually a Kinetic.Group of shapes)
• that's why i need a canvas
• items/shapes need to be highly dynamic in the sense of updating any properties (text and x/y coords for now)
• that's why i need some so called MVVM framework

The question in general: how to build all this ?

The particular stuck in the realization i chose: how to make a veiw --> model values update. or in terms of the the libs in question: how to update shapes properties (e.g. text of the Kinetic.Text obj) from the ng-model directive ?

Many thanks in advance !
