I debugged the issue and it is happening because of following code: form.$.submit = form.$.submit, function( originalSubmit ) {

return function() {


For IE, the DOM submit function is not a function, so we need third check. if ( originalSubmit.apply )

originalSubmit.apply( this );





It works fine after I set the form.$.submit = null; in destroy.

I'm having trouble reproducing this one. Could you provide a heap snapshot that demonstrates this issue?
