OnReset() funcionality

Hello everyone

I am trying to execute OnReset() function in which is implemented reset position of some components
(reason is because those are physics objects in VR and when they stay in basic container before resetting, they spawn not at starting position defined by me but on 0,0,0 coordinates).

For some to me unknown reason, code written by me works if it is not in Reset function but don’t work
in Reset function.

This one works and result looks like this

for i in range(0, 10):
    zel = app.findComponent("Válec_Z #" + str(i + 1))
    zel_mat = zel.PositionMatrix
    mod = app.findComponent("Válec_M #" + str(i + 1))
    mod_mat = mod.PositionMatrix
    cer = app.findComponent("Válec_Č #" + str(i + 1))
    cer_mat = cer.PositionMatrix

    for j in [zel_mat, cer_mat, mod_mat]:
        j.setWPR(0, 0, 0)

    vec_zel = vcVector.new(880.0, -1740.0 + 90 * i, 800.0)
    vec_cer = vcVector.new(740.0, -1740.0 + 90 * i, 800.0)
    vec_mod = vcVector.new(600.0, -1740.0 + 90 * i, 800.0)

    zel_mat.P = vec_zel
    cer_mat.P = vec_cer
    mod_mat.P = vec_mod

    zel.PositionMatrix = zel_mat
    cer.PositionMatrix = cer_mat
    mod.PositionMatrix = mod_mat

app.render()
sim.update()

And this code is the same but in OnReset() function and after resetting simulation it goes to this state which is starting situation.

def OnReset():
  print("Hello")
  for i in range(0,10):
    zel = app.findComponent("Válec_Z #"+str(i+1))
    zel_mat = zel.PositionMatrix
    mod = app.findComponent("Válec_M #"+str(i+1))
    mod_mat = mod.PositionMatrix
    cer = app.findComponent("Válec_Č #"+str(i+1))
    cer_mat = cer.PositionMatrix
    
    for j in [zel_mat,cer_mat,mod_mat]:
      j.setWPR(0,0,0)
    
    vec_zel = vcVector.new(880.0,-1740.0+90*i,800.0)
    vec_cer = vcVector.new(740.0,-1740.0+90*i,800.0)
    vec_mod = vcVector.new(600.0,-1740.0+90*i,800.0)
    
    zel_mat.P = vec_zel
    cer_mat.P = vec_cer
    mod_mat.P = vec_mod
    
    zel.PositionMatrix = zel_mat
    cer.PositionMatrix = cer_mat
    mod.PositionMatrix = mod_mat
    
    print (zel_mat.P.X,zel_mat.P.Y,zel_mat.P.Z)
  getApplication().render()
  getSimulation().update()

Is there any solution for my problem or is OnReset function special in something ?
