[ROOT] Title of TF2's

While on the subject of titles....  I have a simple TF2 and I want to
change the associated TPaveText from holding the formula to holding a
text label.  Here is a script:

 {
     gROOT->Reset();
     TCanvas* canvas = new TCanvas("oscprob","Survival Probability");
     canvas->cd();

     oscprob = new TF2("oscprob","1-sin(1.27*y*731.0/x)^2",0.0,10.0,1e-3,10e-3);
     oscprob->Draw("COL");
     canvas->Modified();
     canvas->Update();

     TPaveText* pt = (TPaveText*) canvas->GetPrimitive("title");
     pt->Clear();
     pt->AddText("Survival prob");
 }

However the formula remains.  I have also tried various interactive
maneuvers on the TPaveText.  I can succeed in clearing or appending
the text, but not replacing it.  What am I doing wrong?

Thanks,
-Brett.
