Issue with accordion display in JQuery Mobile page

Issue with accordion display in JQuery Mobile page

Hi All,
      I have a collapsible set in a jquery mobile page to which multiple collapsible structures are appended dynamically. After adding all the dynamic contents even when i do $("# walk_sections ").trigger('create') only one of the collapsible content has that accordion structure visible and all the remaining collapsible contents(<div data-role="collapsible">) appear as open content without the accordion structure. This issue occurs more prominently in IE rather than other browsers. Iam using IE9. The collapsible set code is mentioned below to which multiple collapsibles are appended
<div data-role="collapsible-set" data-content-theme="c" data-mini="true" id="walk_sections">
Can someone help me on this.
