Correct use Event.on form submit

[kstubs]

Is this correct?

this.__z__handleSubmit = this.form.on('submit', this.__handleSubmit.bindAsEventListener(this)); 

Where:  __z__handleSubmit is my Event Handler

Where: __handleSubmit is the class method to bind to

Is the bindAsEventListener necessary?  I want to get back the Event Handler so I can later destroy it with:

this.__z__handleSubmit.stop();

this.__handleSubmit.bind(this) should be enough

Victor,

That is not conveniently tied to any event handler, so what is the convenient means of disconnecting it, as in __eventHandler.stop(); ?

Sorry, I've not completely understood this phrase. I'll repeat myself:

// start observer - bindAsEventListener isn't needed

this.__z__handleSubmit = this.form.on('submit', this.__handleSubmit.bind(this));
// stop observer

this.__z__handleSubmit.stop();
