EventListener doesn't work

Hi, 
I have written a Swing component which wraps JSVGCanvas, and I would 
like to capture DOM elements using eventlistener. 
 
So some source code of the program is as follows:

    @Override
    public void run() {
	try {
            while (true) {
               // Only update the DOM while rendering is not in progress
               Element newNode = null;
               Element parent = null;

               UpdateManager um = jSVGCanvas1.getUpdateManager();
               doc = um.getDocument();
               Element svgRoot = doc.getDocumentElement();

                synchronized (updateList) {
                        switch (EditType) {
                            case ADD: {
                             Element newNode =
doc.createElementNS(SVGDOMImplementation.SVG_NAMESPACE_URI, "line");
                               newNode =
doc.createElementNS(SVGDOMImplementation.SVG_NAMESPACE_URI, "line");
                               newNode.setAttributeNS(null, "id",
"currentdrawing_111123");
                               newNode.setIdAttribute("", true);
			       newNode.setIdAttribute("id", true);
                               newNode.setAttributeNS(null, "stroke",
"black"); 
                	       newNode.setAttributeNS(null, "stroke-width", "1");
               		       newNode.setAttributeNS(null, "x1", "7");
			       newNode.setAttributeNS(null, "y1", "22");
               		       newNode.setAttributeNS(null, "x2", "115");
			       newNode.setAttributeNS(null, "y2", "223");
 
			       parent = svgRoot;
                               parent.appendChild(newNode);                             
                               break;
                            }
                            case UPDATE: {

                                break;
                            }
                            case REMOVE: {

                                break;
                            }

                        }

                    } else {
                        updateList.wait();
                    }
                }
                if ((parent != null) && (newNode != null)) {
                    parent.appendChild(newNode);
                    if (!buttonGroup1.isSelected(cursorbutton.getModel())) {
                        t1 = (EventTarget) doc.getElementById
(newNode.getAttribute("id").toString());
                        t1.addEventListener ("click", new
OnClickCircleAction (), false);
                     }

                } else {
                    log.log(Level.WARNING, "Unknown parent element ID {0},
element {1} not added", new Object[]{parent, newNode});
                }

                // Check to see if we emptied the list this run
                if (updateList.size() == 0) {
                    rendering = new Date().getTime();
                    // Resize the SVG Canvas
                    svgRoot.setAttribute("width",
String.valueOf(getWidth()));
                    svgRoot.setAttribute("height",
String.valueOf(getHeight()));

                    log.info("--- Forcing Canvas Repaint ---");
                    // This can take a while, and putting it inside the
synchronized
                    //  block seems to deadlock due to updates being
enqueued
                    um.forceRepaint();


                }
            }
        } catch (InterruptedException ex) {
            log.warning("Caught Interrupted Exception, exiting update
thread");
        }

     		}


But my event handler is never called. 
I do not understand why it is not called. 

Using JDK 1.6.25 and Batik 1.7. 

Any suggestions would be greatly appreciated.
