Add row to table and send to server, post table via jquery to php

I'm trying to make a table where I can add a new row with a button click and then send the table to the server so it remembers the information on page refresh. Below is a button which successfully adds a row to a table with the current time. However, when I send the table to the server via the "Send to Server" button it does not echo back the updated table, only the original. It would be such a relief to get this figured out.

HTML:

<input type = "button" id = "send" value = "Send to Server" />
<input type = "button" id = "add" value = "Add Row" />
<table class="table table-striped">
        <tr>
            <td><h2>In</h2></td>
            <td><h2>Out</h2></td>
            <td><h2>Total</h2></td>
        </tr>
        <tr>
            <td>InData</td>
            <td>OutData</td>
            <td>TotalData</td>
        </tr>
</table>

JS:

<script language="javascript" type="text/javascript" src="jquery-1.8.2.js"></script>
<script language="javascript" type="text/javascript">

$("#add").click(function(){

    var dt = new Date();
    var time = dt.getHours() + ":" + dt.getMinutes() + ":" + dt.getSeconds(); //set variable to current time
    $('table > tbody:last').append('<tr><td>'+time+'</td><td></td><td></td></tr>'); //add row to table with current time

});

$(function(){
    var dataArr = [];
    $("table").each(function(){
        dataArr.push($(this).html());
    });
    $('#send').click(function(){
        $.ajax({
          type : "POST",
          url : 'timesheet.php',
          data : "content="+dataArr,
          success: function(data) {
              alert(data);// alert the data from the server
          },
          error : function() {
          }
         });
    });
});
</script

PHP (timesheet.php):

<?php 
    echo $_REQUEST['content'];
?>

Solution

Use .on() instead of .click()

<script language="javascript" type="text/javascript" src="jquery-1.8.2.js"></script>
<script language="javascript" type="text/javascript">

$(document).on('click', '#add', function(){

    var dt = new Date();
    var time = dt.getHours() + ":" + dt.getMinutes() + ":" + dt.getSeconds(); //set variable to current time
    $('table > tbody:last').append('<tr><td>'+time+'</td><td></td><td></td></tr>'); //add row to table with current time

});

$(document).on('click', '#send', function(){
    var dataArr = [];
    $("table").each(function(){
        dataArr.push($(this).html());
    });
    $('#send').click(function(){
        $.ajax({
          type : "POST",
          url : 'timesheet.php',
          data : "content="+dataArr,
          success: function(data) {
              alert(data);// alert the data from the server
          },
          error : function() {
          }
         });
    });
});
</script>

Edited:

The click() binding you're using is called a "direct" binding which will only attach the handler to elements that already exist. It won't get bound to elements created in the future. To do that, you'll have to create a "delegated" binding by using on().

From the documentation of .on():

Delegated events have the advantage that they can process events from descendant elements that are added to the document at a later time.
