Flex Flash event call

Question

Ok, this is probably going to be a little confusing, but Im
still relatively new with Flash/Flex2 so Ill do my best. I have an
Flash asset which is a map of the United States. The asset has its
own actionscript file that handles the mouseover, mouseout, etc
events. No, I am trying to use this asset in a flex application as
a means for users to click on a state and see a list of postings
from that state. So far, all this works great.
Now, what I want is to have the flex query a web service and
compile a list of all the states that currently have postings and
then have the map show a different color for those states.
I'm not really sure if I need to create a property in the
flash actionscript file and call that from the flex, or what. I
want my application to be loosely coupled and I was thinking I
could have flex dispatch an event but I dont know if the Flash
Asset is able to capture the event and then use it to turn the
appropriate states on.
Is there a better way to handle this? I like having the
assets handle their own behavior and contain the methods to perform
the switch, but I dont what is a good way to implement this.
Thank you all SO MUCH!!!

I couldn't use 'complete' becouse then the function doesn't execute. For example:
<mx:SWFLoader id='flashMCinstance' source='{myMC}' complete="loaderCompleteHandler"/>
private function loaderCompleteHandler (event:Event) :void
     flashMCinstance.content.addEventListener('myEvent', myFunction);
or
<mx:SWFLoader id='flashMCinstance' source='{myMC}' complete="loaderCompleteHandler () "/>
private function loaderCompleteHandler () :void
     flashMCinstance.content.addEventListener('myEvent', myFunction);
doesn't execute this function, but the creationComplete="loaderCompleteHandler()" with loaderCompleteHandler():void work. I don't know why, becouse I can see the MC on stage loaded, so it should be completed by then.
In debugger I see that content variable of this SWFLoader is "nameOfMyApp_myMC" - the 'myMC' is class name for source of this SWFLoader. So it appears that everything is ok, but it still doesn't work.
