Emit custom notify in Vala

custom-emit-notify.vala

using GLib;

public class TestClass : GLib.Object {
	public string test1 {get;set;default = "test1";}
	//Ths one won't emit on assignment
	[CCode (notify = false)]
	public string test2 {get;set;default = "test2";}

	public static void main (string[] args) {
		var test = new TestClass ();
		test.notify["test1"].connect (() => GLib.print ("test1 notification\n"));
		test.notify["test2"].connect (() => GLib.print ("test2 notification\n"));
		test.test1 = "Ahoy";
		test.test2 = "Újale";
		test.test2 = "Ajúa";
		ParamSpec pspec = ((ObjectClass) typeof (TestClass).class_ref ()).find_property ("test2");
		GLib.print ("First try, will not work %s\n", pspec.name);
		test.notify(pspec);
		GLib.print ("second one, this is how it works");
		test.notify["test2"] (pspec);
		return;
	}
}

Thanks a lot. I didn't know this is possible and I used it to implement notifications on a derived property (no setter).
