Event Handler for Autocomplete and Click Off

Can you include some changes that will help event handling with validation?

I added a local method to handle updates
`// update method for autocomplete
function update() {
$(this).niceSelect("update");
}`

In the create_nice_select method, I added a binding that will call that local method when the select is changed:
`$select.bind("change", update);`

I unbound it back up in the string method handler (so when you call the destroy method:
`$select.unbind("change", update);`

lastly, I added the blur functionality to the part when you close when clicking outside.
`$('.nice-select').prev('select').trigger('blur');`

Thanks,
Robert

Find the plugin source containing create_nice_select and the string method handler. Review the proposed change, including the autocomplete update binding, its removal during destroy, and triggering blur when clicking outside. Done means validation-related change and blur events behave correctly without leaving a handler bound after destruction.
