If you want your cell to handle events you need to set those events as
consumed by defining a constructor like
public ClickableSafeHtmlCell(SafeHtmlRenderer<String> renderer) {
super(renderer, "click");
}
But do not reinvent the wheel,
http://google-web-toolkit.googlecode.com/svn/javadoc/2.5/com/google/gwt/cell/client/ClickableTextCell.html
is
already there (that also is a safehtmlcell).
