void BreakOut()

//--- Create a button to send custom events
   ObjectCreate(0,buttonID,OBJ_BUTTON,0,100,100);
   ObjectSetInteger(0,buttonID,OBJPROP_COLOR,clrWhite);

I Don't know why Expert doesn't delete the button.

Please someone help me find why

You have to pass the ID to the function otherwise it won't know what button

void OnChartEvent(const int id,const long &lparam,const double &dparam,const string &sparam)
{
      if(sparam==buttonID) // Activation Button
        {
         Print("Button Pressed");
         Action_Button(buttonID);
         ObjectSetInteger(0,buttonID,OBJPROP_STATE,false);
        }
}
void Action_Button(string buttonID)
{
    Print("Button Pressed Subroutine");
    ExpertActive=true;
    ObjectDelete(0,buttonID);
}
