[Rails] jQueryUI autocomplete (Rails 3.1): can't get source as url to work

Hey,

I'm able to duplicate everything in Ryan Bates' screencast on jQueryUI autocomplete (#102), except for the piece that calls the server for completion data.

Here is my view html:

<input data-autocomplete-source="/searches" id="search-markets" name="search-markets" placeholder="market keyword and/or location" size="50" type="text" autocomplete="off">

Now, this coffeescript works...

$('#search-markets').autocomplete

source: ['foo', 'food', 'four']

...whereas, this coffeescript trying to tap the server...

$('#search-markets').autocomplete ->

source: $('#search-markets').data('autocomplete-source')

...results in http POST calls to the root and not the data-autocomplete-source value of '/searches'.

Bates's railscast uses a textfield in the context of a RESTful form, but I don't expect this difference between his code and mine should explain my unexpected POST.

Any thoughts?

Lille
