title: Move an object with Create.js
body: <p>I'm trying to move a line in erase.js I read some thread with this issue, but nothing works for me. The problem is that, I can manipulate some properties like label position, but not the line position.
  Just now the creation of my line is:</p>
  
  <pre><code>var result = {};
                  //Generation of the line
                  result.line = new createjs.Shape();
                  result.line.graphics.setStrokeStyle(3);
                  result.line.graphics.beginStroke("#000");
                  result.line.graphics.moveTo(o[0].__dragger.x + 24 , o[0].__dragger.y);
                  result.line.graphics.lineTo(o[1].__dragger.x - 24, o[1].__dragger.y);
                  result.line.graphics.endStroke();
                  //result.line.shadow = new createjs.Shadow("#000000", 5, 5, 10);
  
  
  
                  //Add the neighbours
                  result.neighbours = o;
  
                  //Add the label
                  result.label = new createjs.Text("line", "", "#000");
                  result.label.textAlign = "center";
                  result.label.y = 80;
                  result.label.x = 200;
  
                  //Add the dragger and extra properties
                  result.type = "connector";
                  result.__dragger = new createjs.Container();
                  if(id == "")
                      result.__dragger.id = "L" + guid();
  
                  result.__dragger.addChild(result.line, result.label);
                  stage.addChild(result.__dragger, result.line);
  
                  result.__dragger.on("click",function(evt) {
                      Shape.create("square", [], "Assignament");
                  });
  
                  stage.addChild(result.__dragger);
                  stage.update();
  myShapes.push(result);
  </code></pre>
  
  <p>If I execute:</p>
  
  <pre><code>myShapes[2].label.y = 200;
  myShapes[2].label.x = 300;
  stage.addChild(myShapes[2].__dragger);
  stage.update();
  </code></pre>
  
  <p>The position is updated, but if I try with:</p>
  
  <pre><code>myShapes[2].line.graphics.moveTo(300,4000)
  stage.addChild(myShapes[2].__dragger);
  stage.update();
  </code></pre>
  
  <p>The object is not updated. Some idea??</p>
