> I have a requirement to add/remove tabs to TabBar component at runtime.
> Despite the bracketed binding is fixed now to TabBar, it's failed to update it's view
on any update to bindable source; though it's a second big expectation from a binding feature.
> I tried to look into the TabBar source and then into {{TabsItemRendererFactoryForArrayData.as}}
file. I seen there is a change listener added to the collection/source:
> {code}dataProviderModel.addEventListener("dataProviderChanged", dataProviderChangeHandler);{code}
> I noticed that changes to the source never fires the above method, though. Thus, I forcibly
dispatches the event after any changes to the source, i.e. addition to the source, that does
adds a new tab like block to the TabBar component, but without any working functionality to
it.

> In above image, "CHIPS" added after a button click event, but I noticed it gets added
without mdl tab styles on it. Furthermore, the TabBar seems completely broken, no section
change occur, no selected tab style occur (the red line beneath the selected tab), and clicking
any particular tab add the 'tabId' to the address bar (as shown in the image).
> I've attaching herewith a basic TabBar project which has 3 buttons - to modify an entry,
remove an entry and add an entry to the TabBar component. TabBar's data source is done in
a fashioned manner with bracketed binding.
> Thanks!
