Why does 'on change' fire when record view is loaded?

Question

I must be missing something...

Why do on change events fire when the record view is loaded before that field is indeed changed?

How can I stop the execution of an on change until the field is actually changed?

thanks,
Francesca

You can add the onchange event like this , so that this will trigger only on actual field change this.model.once( "sync", function() { this.model.on( "change:{field_name}", this.{function_name}, this ); }, this );
