I don't think there is a way to remove the text property with the 
current version. Could you please file a ticket and we'll try to fix 
that in the next release? It will likely be done by calling 
$class->setText(null)

The following should work:

$class->setText("([FIELD_NAME])");

Okay, I'll admit that was not obvious. The TEXT parameter works 
differently from regular attribute binding. It actually goes through the 
logical expression parser, that's why there is a special setTExt() 
method and the round brackets are required.
