How to change Id of a dynamically created child element?

Question

Hi,
I would like to change the id of the dynamically created elements in order to work easily with their later. Currently, edge automatically generate an random id like "eid_1376057792551" for each element.
There is my code :
         sym.setVariable("labels", {
                   content2: "Visiteur",
                   content3: "Exposant",
                   content4: "Organisateur",
                   content5: "Contact",
                   content6: "Connexion"
         // Clear initial state
                              sym.getSymbol("tab").deleteSymbol();
                              // Find all large symbols in the library
                              var prefix = "content"; // content1, content2 ... content99
                              var allTabs = [];
                              var symbolDefns = sym.getComposition().symbolDefns;
                              for (var key in symbolDefns) {
                                if (symbolDefns.hasOwnProperty(key) && key.search(new RegExp(prefix+"[0-9]{1,2}"))!=-1 ) {
                                         var tab = sym.createChildSymbol( "tab", "navigation" );
                                         tab.setVariable("contentId", key);
                                         allTabs.push(tab);
                                         tab.$("btnLabel").html( sym.getVariable("labels")[key] || "" );
                                         $tabEl = tab.getSymbolElement();
                                         $tabEl.data("sym", tab);
                                         $tabEl.css({float: "left", margin: "0 -1px 15px 0"});
                                         $tabEl.click(function(evt){
                                                  var tabSym = $(evt.currentTarget).data("sym");
                                                  $.each(allTabs, function(index,item) {
                                                            if (item != tabSym) { item.stop("normal"); item.setVariable("active", false); }
                                                  var $content = sym.$("content").empty();
                                                  sym.createChildSymbol(tabSym.getVariable("contentId"), "content");
Thank you .

hi -  trying to get this to work with no luck.
a simple example as i understand it:
var test = sym.createChildSymbol("rect", "Stage");
test.attr("id","test2");
would that work in changing the id of the newly created symbol to test2?
thanks!
