Hi.
I'm trying to render an Ajax response with a specified template.

My controller code looks like this:

$data = array(
'Items' => array( 'Test1', 'Test2', 'Test3' ),
'Pairs' => array( 'Foo' => 'Bar' ),
);
return $this->customise($data)->renderWith('AjaxResponse');

Now, in the template, I can use the control Items to get the iterator:

<% control Items %>
<item />
<% end_control %>

So it prints three separate items, but I am unable to get their contents.
How can I print out 'Test1','Test2','Test3' in Items control?
I also tried to use $Pairs.Foo, but it still didn't work.
So I've got two questions:

1. How should I construct the $data array to use it as controls in the template?
2. Is it possible to get the keys, not only values, from a control?

Works perfect, thanks a lot!
And for getting the keys, not only values, from a control - I changed it to:

foreach($arr as $key => $val) {
$data->push(new ArrayData( array( 'Key' => $key, 'Value' => $val ) ));
}

So now I can use:

<% control Items %>
<item id="$Key"><![CDATA[$Value]]></item>
<% end_control %>

Thank you very much!
