Bug fix

[laPingu87]

HI!
I find your useful plugin and I adapted it to my situation.
I found this bug: when you add text in the field not typing (for example selecting old typing with autocomplete), it is not adding the class 'populated'. I used Chrome.
I fix it whit the following code:
input.on('change', function(){
if(input.val()!= ''){
element.addClass( settings.populatedClass );
}
})

Hoping you will like it :)
