ActionScript 3.0 :: Call A Function Using Array Index?

I've defined an array which stores the function name, like this:
 
var aresetButtonTop:Array = new Array(resetTop1,resetTop2,resetTop3,resetTop4,resetTop5);  
 
Then I have a button named"btnresetTop" which when clicked will call one of the five functions stored in the above array(aresetButtonTop). The functions are called at run-time depending upon some conditions. I need to figure out how I can call those functions using the array index. I'm using the following code to call the function. The value of i has been already calculated.

btnresetTop.addEventListener(MouseEvent.CLICK, aresetButtonTop[i]);
 
After doing this I'm getting the following error when I click the button:
 
TypeError: Error #2007: Parameter listener must be non-null.    at flash.events::EventDispatcher/addEventListener()    at gallerytest_fla::MainTimeline/thumbTopClick()
 
Note: thumbTopClick() is a function inside which all these codes are written.
 
I need to find out whether it is posible in AS3 to call a function name using the array index or not.
