alert("HI");
});

I think I'm wroing something because I show nothing. Anyone can help me?

It is working fine. If you didn't put your code in $(document).ready(function() { //code } See jsfiddle.net/harishkommuri/yb4yp29z — Harish Kommuri

Have you wrapped your javascript code into $(document).ready()? — Reporter

You could try something like this :

$(document).on('click', '#aggiungiDomande',function(){
    alert("HI");
});

If your button does not exist when your code is executed, no event wil get bound to it. You can read more about event binding here : http://api.jquery.com/on/
