Reloading HTMLLoader content from another window

I'm writing an AIR app using JavaScript and I am creating a window using air.HTMLLoader.createRootWindow(). When an action happens in this new window I need to refresh the content in all the other app windows, but I don't know how to reference the other windows in a way to reload them, this is my line of thinking on what I need to do:

for (var i in air.NativeApplication.nativeApplication.openedWindows) {     var w = air.NativeApplication.nativeApplication.openedWindows[i];     var htmlLoader = ?     htmlLoader.reload();
}
