JQuery ajax can't find elements in returned HTML

Programmer Question

I have a simple

$.ajax({
 url: someUrl, 
 method: 'get',
 dataType: 'html',
 success: function(data) { 
            $('#someId').append($(data));
          } 
 });

The problem is I can't find elements simply within the returned data. If there's an input with id="myInput" I can't get it with $('#myInput') or $('input[id=myInput]'). I CAN find it with:

$('input').each(function(i,e){ if($(e).attr('id') == 'myInput'){ doStuff(e); } });

But who wants to do that each time? I saw this question but the solutions provided didn't work for me. In addition to what's up there I've tried

$('#someId').html(data);
$(data).appendTo($('#someId'));

and I'm using jQuery 1.4.2. Thoughts, suggestions?
