It is impossible to revert effect of $.fn.model(m)

[LazyDev2k]

The method $.fn.model(m) does two things:

1. Adds a model instance to $.data(element, "models")
2. Adds a model-specific class to the element

Unfortunately there is no convenient way to undo this. So if we bound a model to element we can't unbind it (and replace with other model).

I think that there should be a method like $.fn.unbindModel(m) that will revert effect of the $.fn.model(m).

Why do you need this? Typically, if I am swapping a model on an instance, it's through a controller.

Do you mean something like

$('#element').model('remove');

Or maybe

$('#element').model(null);

?

[LazyDev2k]

I mean

$('#element').model(null);
However this will never work because effect of $.fn.model depends on type of specified model.

[justinbmeyer]

null could remove all model instances (found in data.models)

Buuuuuuuuuuuuuuuut ... I'd still like to know why you need this.

We have an analog of select control. User may select any value of the list. We decided to bind selected value (instance of $.Model) to the select itself. And this worked quite well. However we met a case when we need to clear selection. So this ticket came to life.

I can believe that this may be not intended usage of $.fn.model method but in our case it seemed to be the most appropriate. Correct me, if I'm not right.

Also please notice that I not need to remove all model instances but only a specific one.
