Reload functionality

[aneguzman]

I don't know if this enhancement request has already been submitted, but it would be really nice if the library has a reload method available. The thing is that I was using this library in my project and needed to implement the autocomplete functionality in a form that that data will be filled by a scanner. Since the scanner use the paste event on the text input, the autocomplete functionality did not workout pretty good with it because it is waiting for a keyword to be pressed so I had to implement a reload method by myself in order to get it done. The idea is to have a reload method that can take the input value and reload the autocomplete functionality.
