Dynamic List in ListExample is not Dynamic

Hi,

In /examples/royale/ListExample/src/main/royale/MyInitialView.mxml, there is a 'Dynamic List' with a list of states and an Add/Remove button below.

In 0.9.4 this list didn't render anything, since there were no Renderer beads linked to it. In the develop branch, there is now a linked to it, but that only renders the initial state. The Add and Remove buttons still don't work.

I tried replacing the bead with a , but that only made the Add button to work. I also added the , but the Remove button still doesn't work.

```

Full example, see: https://github.com/apache/royale-asjs/tree/c2bca9ab3d8fa530d0f922605db10ec9bf6c1e4e/examples/royale/ListExample/src/main/royale

Open /examples/royale/ListExample/src/main/royale/MyInitialView.mxml and run the ListExample to reproduce the Dynamic List behavior. Inspect the renderer beads and the Add/Remove button wiring described in the issue. Done means the list renders its initial states and updates correctly when both Add and Remove are used.
