"data-filter" attribute in "collapsible-set" (version 1.2.1)

Hi all !

I would like to know if it possible to have a data-filter" attribute to a "collapsible-set" in version 1.2.1 of jquery mobile ?

It doesn't run in my code

(an extract code)

<div data-role="content" data-theme="b">
    <div data-role="collapsible-set" data-filter="true" data-filter-placeholder="Search a car :">
        <div data-role="collapsible" data-iconpos="right" data-collapsed-icon="arrow-r" data-expanded-icon="arrow-d" data-filtertext="honda">
            <h3>HONDA</h3>
   <p>model : </p>
   <p>Motor :</p>
   <p>Color :</p>
    <div data-role="collapsible-set" data-filter="true" data-filter-placeholder="Rechercher un produit...">
        <div data-role="collapsible" data-iconpos="right" data-collapsed-icon="arrow-r" data-expanded-icon="arrow-d" data-filtertext="Acura">
            <h3>ACURA</h3>
