Question

I have an external javascript library which triggers on the change of a textarea, formats it, etc.

However, when KnockoutJS sets the value to the textarea, the change event isn’t fired. Simplified Fiddle of my problem. Is it possible to fire the change event when Knockout updates the value of my textarea?

Rather than trying to force Knockout to work with change events you can setup a subscription on the underlying observable. Like this: http://jsfiddle.net/EZC9E/1/

this.text.subscribe(function(newValue) {
    alert('Text is changing to ' + newValue);
});
