Remove a StaticText-object

I am able to make my StaticText-object invisible by setting the visible option to false (goes away),
but I don’t seems to be able to remove it using removeChild.

This is how I access it:

var child:StaticText = container.getChildAt(i) as StaticText;

And what I want to do is to remove it completely, not just make it invisible. So I use this:

container.removeChild(child);

This gives no errors, but the text is still visible!
I tried removing other stuff from the container, like Sprites, and they all goes away.
It is just the StaticText-object that won’t go away.

Any help really appreciated!
