从以前的td获取文本(Get text from previous td)

 我有一个按钮，当单击时，动态构建一个简单的表。 在第二个td ，插入一个按钮以及一些文本。 
 
<input type = "button" id = "search" value = "Search">
<div id = "searcharea"></div>   
 
$('#search').on('click', function() {
    $('#searcharea').html('<table id = "myTable"><tr><td>Some Text</td><td>Blah Blah<br>Blah Blah<br><input type = "button" value = "Get Text"></td></tr></table>');
});
 
 我要做的是在点击“获取文本”按钮时从前一个td获取文本。 这是我尝试过的： 
 
$('#myTable').on('click', 'input', function (event) {
    var prevCell = $(this).closest('td').previous('td').text();
    alert(preCell);
 });
 
 我认为答案很简单，但我没有看到。 救命。 的jsfiddle 

I have a button that, when clicked, builds a simple table dynamically. In the second td, a button is inserted along with some text.
 
<input type = "button" id = "search" value = "Search">
<div id = "searcharea"></div>   
 
$('#search').on('click', function() {
    $('#searcharea').html('<table id = "myTable"><tr><td>Some Text</td><td>Blah Blah<br>Blah Blah<br><input type = "button" value = "Get Text"></td></tr></table>');
});
 
What I'm trying to do is to get the text from the previous td when the "Get Text" button is clicked. Here's what I've tried:
 
$('#myTable').on('click', 'input', function (event) {
    var prevCell = $(this).closest('td').previous('td').text();
    alert(preCell);
 });
 
I think the answer is a simple one, but I'm not seeing it. Help. JSFIDDLE
