jQuery按名称选择选择器，不返回所选值

Question

I'd created a fiddle and its working well. Also, it was working proper on my system until I'd uploaded it to server. The actual problem I'm getting is, wherever I'd used $('select[name=propType]').val() it always returning Residential .
I specially need that value on line 76 of javascript in fiddle .

Why it is not returning the exact propType selected value on my localhost ? I'd used proper IDs wherever expected.
Any reason of such behavior?

UPDATE
The same code as of fiddle is not working on my site.

line 75 in fiddle-javascript
$('select[name=propType]').val() always returning Residential . Why?

Answer 1

Don't know why $('select[name=propType]').val() not properly working well with me.
I'd changed those selectors with id as $('#propType').val() and $(this).val() applicable where needed.

Answer 2

$('#property').change(function () 

Please bind using

  $("body").delegate("#property", "change", function() {
   // your functionality come here
    });
