Edge Animate CC :: Collision-Detection With CSS And JQuery - How To Start Animation

I want to have some kind of collision-detection within two symbols. So when one symbol collides with another there will appear be text like "squash" or something.
 
I haven't found anything about collision-detecting in edge animate, but I thought I could handle it with looking for the same css-parameters of both symbols. Obj1 is moving to Obj2 on a motion path. Now I want to have a Text, when it reaches Obj2.So I tried it like this:
 
var positionobj1 = sym.$("obj1").css("left");
var positionobj2 = sym.$("obj2").css("left");
 
if (positionobj1 == positionobj2){
sym.play("Text");
}
