Change event not fired when field is cleared by plugin

[lakshme]

When a value is entered in the field greater than the specified vMax, then the autonumeric plugin automatically clears the field by setting value=''
But it does not fire a change event at this time.
I need to listen to and bind the value of this field to an attribute in my class. Since I have no way of knowing that the value has been cleared to '' (since there was no event fired), I still have the old value in my attribute.

So made a change locally where we fire the event in all cases as follows :

if ( groupedValue !== origValue ) {
iv.val( groupedValue );
iv.change(); ---------------------------------- my change
}
if ( groupedValue !== holder.inVal ) {
iv.change();
delete holder.inVal;
}

Please can you have a look at this and provide a fix ? Thanks. Am using version 1.7.1.
