Detect changed input text box

I’ve looked at numerous other questions and found very simple answers, including the code below. I simply want to detect when someone changes the content of a text box but for some reason it’s not working… I get no console errors. When I set a breakpoint in the browser at the change() function it never hits it.

$('#inputDatabaseName').change(function () { 
    alert('test'); 
});

<input id="inputDatabaseName">
