Task Description:
There is a button "Start search", when clicked, the search starts. After that, the button changes the text to "Stop Search", and if you click, the search stops.
I think to implement it this way: after clicking the button to sign it on different handlers. But I do not understand how to do it.
There is a trigger that allows you to change the Holy Island, but not the signature on the event.
Question: maybe there is a more correct way?
