just need to execute a function - myFunction() when roll over a button

i can do it coding the button like so:

[AS]on (rollOver) {  
\_root.myFunction(this);  
}[/AS]

or code it in the root where i defined the function, like so:

[AS]myButton.onRollOver = function() {  
myFunction(this);  
}[/AS]

the thing is, i’m using this for a tween class animation, and when i code it directly in the button it works fine

can i write this AS diferent way?!  
myButton.onRollOver = function() {  
myFunction(this);  
}

thx
