Dynamic data insert into a plain content Div and jquery Mobile

Dynamic data insert into a plain content Div and jquery Mobile

I need a little Help with a call to add content dynamically.
 
I'm trying to load a page that dymanically generates a table into a div with jquery mobile:
 
Taking the date value from the datepicker and I have a routine to generate the url:
 
 <div data-role="content"> 
  <form action="" method="post" onsubmit="javascript:getData(this);" >
   <div data-role="fieldcontain">
           <input type="date" name="eventdate" id="eventdate1" value=""  style="display:none;" />
           <button type="submit" data-theme="b" name="submit" value="submit-value">Submit</button>
   </div>  
  </form>
  <div id="theevent_data">
   <p>the event data<p>
  </div>
 </div>










 
So basically I'm creating this url: libcalendar_day.asp?nMonth=03&nDay=23&nYear=2011 (for instance)
 
in getData() and trying to retrieve the result and insert it in "theevent_data"
 
But no combination seems to work. 
 
Any help on syntax for a call to do this would be very appreciated.
