Is it possible to add jQuery UI theme (Combobox, button) to dynamic elements -

ex: dynamic select box or button (from ajax response) when inserted page should render in jquery ui combobox style or jquery ui button style.

$.get("someurl", function(html){   $("p").append(html);   // @ point selectbox & button should rendered   // jquery ui combobox & jquery ui button  }

response html contains form list of textfield, selectbox & button

<select name="scope" >  <option value="in">in</option>  <option value="out">out</option> </select>  <div class="buttoncontainer">  <button name="save">save</button>  <button name="cancel">cancel</button>                </div> 

after html appended want style select box using $("select").combobox(). in main page (js file) have added below line in document ready method.

 $("select").combobox()   $("button").button()  

like jquery has .on() attach event handler function dynamic elements. in same way possible add ui theme (combobox, button) dynamic elements ?

updated:

i guess triggering event when ever page html loaded (by ajax). http://jsfiddle.net/ecj8n/

$("body").bind( "uirender", function() {     $("select").combobox();      $("button").button() ;            }); 

and ajax response do

$.get("someurl", function(html){   $("p").append(html).trigger("uirender"); } 

isn't there better approach ?
