Hi,
Now If i am correct then you just want to activate an EventReciever on click of button on a Page using Object Model code and you have your Event Reciever already deployed and register in Global Assembly Cache.
To do this just add this code on the button click event on page.
using (SPSite site = new SPSite(SPContext.Current.Web.Url))
using (web = site.OpenWeb())
SPList list = web.Lists["ListName"];
if (list != null)
string className = "YourClassNameSpace.YourClass";
string asmName = "NameOftheAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken={PublicKeyToken}";
web.AllowUnsafeUpdates = true;
//add the added/updated/deleted events to the list.
list.EventReceivers.Add(SPEventReceiverType.ItemAdded, asmName, className);
list.EventReceivers.Add(SPEventReceiverType.ItemUpdated, asmName, className);
list.EventReceivers.Add(SPEventReceiverType.ItemDeleted, asmName, className);
list.Update();
