Calculation on Dynamically created rows using jAutoCalc Plugin

Calculation on Dynamically created rows using jAutoCalc Plugin

Am trying to do multiple simple calculations using the jAutoCalc.js jquery plugin in a form where the rows can be dynamically added or removed. While the calculation works for the first row it is not happening for the subsequent rows. Also I like to sum all the total values using the same plugin and stick it in the 'Sum of Total' input box at the bottom.Thanks in advance for helping me out.

<form name="cart">
   <input value="Add" type="button" />
   <input value="Remove" type="button" />
   <p>
   </p>
   <p>
   </p>
   <table id="dataTable" class="form" border="1">
      <tbody>
         <tr id="row_0">
            <td>
               <input checked="checked" type="checkbox" />
            </td>
            <td>
               <label>
