Is it possible to have clickable drawn elements

Question

I can add a click event to the canvas, but can't figure how to have a click specific to only an object on the canvas can anybody help? I just want to add an event listener to the circles and not the canvas, but I can not figure out how to point to them specifically so i can make them draggable. I included a canvas click function that displays the mouse position when you click the canvas.
var winRes = "dialog {  \
    text: 'test',  \
    margins: 15, \
    alignChildren: 'row', \
    canvas: Custom {  \
        preferredSize: [200, 200], \
        creation_properties: {borderStyle: 'black'} , \
// Window
var win = new Window(winRes);
function color() { return [Math.random(),Math.random(),Math.random(),1] }
// define the graphic property
canvasGraphics = win.canvas.graphics
// do the drawing
win.canvas.onDraw = redraw
win.canvas.addEventListener ('mousedown', down, false);
function down(e){
    curX = e.clientX;
    curY = e.clientY;
    alert("Mouse position: " + curX + ", "+ curY)
function redraw() {
          // creates a red filled square
          canvasGraphics.newPath()
          canvasGraphics.rectPath(0, 0, 200, 200)
          canvasGraphics.fillPath(canvasGraphics.newBrush(canvasGraphics.BrushType.SOLID_COLOR, color(), 1)) // HERE
          canvasGraphics.newPath()
          var dot1 = canvasGraphics.ellipsePath (20, 20, 30, 30)        
          canvasGraphics.fillPath(canvasGraphics.newBrush(canvasGraphics.BrushType.SOLID_COLOR, color(), 1)) // HERE
          canvasGraphics.newPath()
          var dot2 = canvasGraphics.ellipsePath (20, 90, 30, 30)
          canvasGraphics.fillPath(canvasGraphics.newBrush(canvasGraphics.BrushType.SOLID_COLOR, color(), 1)) // HERE
          dot1.onmousedown = dot2.onmousedown = function(){
              var me = this;
              alert(me)
win.show()

Ryan,
Have you looked into trying to use the Web Pane URL for your scenario?
<a href="http://help.sap.com/saphelp_mdm550/helpdata/en/8c/ca6d92fe624549a2809c8d02ab063c/frameset.htm">Web Pane URL</a>

This will allow you to create a URL to search Google for example based on the data contained your fields/attributes. You need to create the custom URL in the Console and then activate the option from the configuration settings in the Data Manager. This will then activate the Web tab for this link, all internal to MDM.
Let me know if you need more detail.
Thanks,
