[X3D-Public] update index in XED xhtml

[Felipe Bordeu Weldt]

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
