jQuery - Iterate through data stored object
<p>I encounter something quite strange while trying to iterate properties of an object stored 
using jQuery data function.</p>

<p>Here is the thing (as an example) :</p>

<pre><code>wrapper.data( 'infos', {
    label: $('input[name*="label"]').val(),
    amount: $('input[name*="amount"]').val(),
    etc..
});
</code></pre>

<p>Then i try to read values using :</p>

<pre><code>$.each( wrapper.data('infos'), function(k,v) {
  console.log(k + ' &gt; ' + v);
});
</code></pre>

<p>And i get a beautiful output like :</p>

<pre><code>0 &gt; undefined
1 &gt; undefined
... 
239 &gt; undefined
</code></pre>

<p>If i output this object as if, i can read properties without any difficulties.
Is it somehow related to jquery caching or something ? </p>
