I found the function that normally does what I am looking for. From 
the book "X3D , Extensible 3D Graphics for web Authors" from Don 
Brutzman & Leonard Daly. Page 359:

"Nevertheless, an additional set_index field with accessType inputOnly 
is also
provided so that index values might be changed at runtime and the 
geometry can be
animated"

But how do I access to this field from javascript?

Thanks.
Felipe
