JavaScript onkeyup event seems to not fire or is ignored

I have this:

txtNew.Attributes.Add("onkeyup", "alert('hi');");

But when I type in the textbox - no alert comes up. I just type and type and no alert ever comes up. Why is this not working?

Tried in IE 11, Chrome 42.0, and FF 37.0. Using .NET 4.0.

Also tried the "onkeypress" event. Same results. I cannot get the alert to come up.

The textbox definition is:

asp:TextBox ID="txtNew" TextMode="Password" runat="server" MaxLength="256

Tried removing the TextMode attribute but the result is still the same.

Ultimately, what I want to do is this:

txtNew.Attributes.Add("onkeyup", "CheckChars()");

Where CheckChars() is my JS script. However when it didn't work, I just put an 'alert()' in there to see if even that would work.
