How To Properly Set Events For Dynamic Xul Elements?

I have a toolbar extension that generates dynamic toolbarbutton and menuitem elements. These items are typically constructed like this: tempMenuItem = document.createElement('menui

Solution 1:

Well, you obviously use addEventListener() method as the suggestion says:

tempMenuItem.addEventListener("command", function(event)
{
  myObject.someFunction();
}, false);

Or somewhat shorter if you also use the Function.bind() method:

tempMenuItem.addEventListener("command", myObject.someFunction.bind(myObject), false);
