Radiobutton widget

Hello.
I'm using jQuery mobile 1.2.0 and the following markup:
<fieldset class="data-types-horizontal" data-role="controlgroup" data-type="horizontal">
   <legend>
      Choose data:
   </legend>
   <input class="data-type" name="cjr-h" id="cjr-h" value="cjr" checked="checked" type="radio" />
   <label for="cjr-h">
      CJR
   </label>
   <input class="data-type" name="languages-h" id="languages-h" value="languages" type="radio" />
   <label for="languages-h">
      Languages
   </label>
   <input class="data-type" name="titles-h" id="titles-h" value="titles" type="radio" />
   <label for="titles-h">
      Titles
   </label>
   <input class="data-type" name="user-position-h" id="user-positions-h" value="user-position" type="radio" />
   <label for="user-positions-h">
      All user positions
   </label>
   <input class="data-type" name="cust-producst-h" id="cust-products-h" value="cust-product" type="radio" />
   <label for="cust-products-h">
      Customer product catalogue
   </label>
   <input class="data-type" name="accounts-h" id="accounts-h" value="accounts" type="radio" />
   <label for="accounts-h">
      Accounts
   </label>
</fieldset>
<fieldset class="data-types-vertical" data-role="controlgroup">

   </label>
   <input class="data-type" name="titles-v" id="titles-v" value="titles" type="radio" />
   <label for="titles-v">

   </label>
   <input class="data-type" name="user-position-v" id="user-positions-v" value="user-position" type="radio" />
   <label for="user-positions-v">
      All user positions
   </label>
   <input class="data-type" name="cust-producst-v" id="cust-products-v" value="cust-product" type="radio" />
   <label for="cust-products-v">
      Customer product catalogue
   </label>
   <input class="data-type" name="accounts-v" id="accounts-v" value="accounts" type="radio" />
   <label for="accounts-v">
      Accounts
   </label>
</fieldset>

Default JQM functionality wraps markup into radiobutton widget - ok, then a click on some unchecked radio turns it to checked state - ok, but then i can't uncheck it by click on it again. There's no additional code used to manipulate the markup above.
