I have a problem with KineticJS – there is no drag on my shape.

What is wrong with my code? – Iam really stuck and need somebody KineticJS-shark.

My code:

<!DOCTYPE HTML>
<html>
<head>

<script src="kinetic-v4.0.4.min.js"></script>
<script>
window.onload = function() {
var stage = new Kinetic.Stage({
container: "container",
width: 1024,
height: 768
});
var layer = new Kinetic.Layer();
var spaceShip = new Kinetic.Shape({

drawFunc: function (context) {

context.beginPath();
context.moveTo(99.3, 161.4);
context.bezierCurveTo(99.3, 143.2, 92.5, 128.4, 84.2, 128.4);
context.bezierCurveTo(83.6, 128.4, 83.1, 128.4, 82.6, 128.6);
context.bezierCurveTo(76.5, 84.1, 53.0, 8.0, 53.0, 8.0);
context.bezierCurveTo(53.0, 8.0, 29.6, 84.0, 23.5, 128.5);
context.bezierCurveTo(23.0, 128.4, 22.6, 128.4, 22.2, 128.4);
context.bezierCurveTo(13.8, 128.4, 7.0, 143.2, 7.0, 161.4);
context.bezierCurveTo(7.0, 179.6, 22.2, 228.9, 22.2, 228.9);
context.bezierCurveTo(22.2, 228.9, 27.2, 212.4, 31.5, 194.9);
context.bezierCurveTo(37.1, 206.7, 44.7, 213.9, 53.0, 213.9);
context.bezierCurveTo(61.5, 213.9, 69.1, 206.5, 74.7, 194.6);
context.bezierCurveTo(79.0, 212.2, 84.2, 228.9, 84.2, 228.9);
context.bezierCurveTo(84.2, 228.9, 99.3, 179.6, 99.3, 161.4);
context.closePath();
context.fillStyle = "rgb(203, 203, 203)";
context.fill();


context.bezierCurveTo(37.9, 97.3, 42.4, 92.8, 48.0, 92.8);
context.bezierCurveTo(53.7, 92.8, 58.2, 97.3, 58.2, 102.9);
context.closePath();
context.fillStyle = "rgb(255, 255, 255)";
context.fill();


},


});


// add the shape to the layer
layer.add(spaceShip);

// add the layer to the stage
stage.add(layer);

spaceShip.setDraggable(true);

spaceShip.on('dragstart', function() {
    console.log("Drag start");      
});

spaceShip.on('dragend', function() {
    console.log("Drag end");        
});




};

    Try this below code

<head>

    <script src="http://www.html5canvastutorials.com/libraries/kinetic-v4.0.3.js"></script>

    <script>
        window.onload = function() {
            var stage = new Kinetic.Stage({

                width: 1024,
                height: 768
            });
            var layer = new Kinetic.Layer();

            var spaceShip = new Kinetic.Shape({
                drawFunc: function (context) {
                    context.beginPath();
                    context.moveTo(99.3, 161.4);
                    context.bezierCurveTo(99.3, 143.2, 92.5, 128.4, 84.2, 128.4);
                    context.bezierCurveTo(83.6, 128.4, 83.1, 128.4, 82.6, 128.6);

            // add the shape to the layer
            layer.add(spaceShip);
