problem of changing parameter of a TF1

Hello,

(using root 5.30 for example)

i occur a problem with a basic minimum example where the parameter of a TF1 (that is fine) is changed, but when drawn, nothing change.

actually, this function has been created from a RooAbsPdf transformed to a TF1, via the asTF(...) method. So it may be the main problem

the minimum example is here
/afs/in2p3.fr/home/e/escalier/public/test

>From the print in the example, we see that everything looks as if the
change of one of the parameter (here the amplitude) is "understood", but when drawing it, it "forgets" this

thanks for any advice
