Enabling jQuery Autocomplete on dynamically created input fields

You must bind autocomplete after adding new elements

$(wrapper).find('input[type=text]:last').autocomplete({
                source: availableAttributes
}); 

See example: http://jsfiddle.net/r08m8vvy/4/

Give the new input an ID and call autocomplete on it. The initial autocompate call you make won't include the dynamically added inputs.

 $(wrapper).append('<div><input id="' + x + '" type="text" name="mytext"/><a href="#" class="remove_field">Remove</a></div>'); //add input box

 $( "input[id="+ x +"]" ).autocomplete({
     source: availableAttributes
 });    

I actually found that a more reliable way was to bind using 'on' with the 'focus' action to init the auto complete based on the field class and destory it on exit. This way it cleans up the garbage and only inits it once you need to.

I was using it with cloning rows though and even doing deep cloning, which would clone the plus and minus buttons for the rows, it wasn't cloning the autocomplete.

var auto_opts = {...opts...}

$('body').on('focus', '.search_field', function(){
    $(this).autocomplete(auto_opts).on('blur', function(){$(this).autocomplete('destroy')});
    });

It also means that you aren't forced into using the last row because it works on the field as you focus on it
