  var allRows = root.getElementsByTagName('tr');//the rows' collection 
  var cRow = allRows[0].cloneNode(true)//the clone of the 1st row 
  var cInp = cRow.getElementsByTagName('input');//the inputs' collection of the 1st row 
  for(var i=0;i<cInp.length;i++){//changes the inputs' names (indexes the names) 
  cInp[i].setAttribute('name',cInp[i].getAttribute('name')+'_'+(allRows.length+1)) 
  } 
  root.appendChild(cRow);

    <td width="10"><input name="button" type="button" value="+" onclick="addRow(this.parentNode.parentNode)"></td> </tr> </table> </form>

You have to use just name of the text box which is added by dynamically.

 $('form').submit(function() {
 var data=($(this).serialize());
 return false;
 });

This function get all the elements value and create one string which is store in data, now data will pass in ajax call.

$('form').submit(function() {
 var data=($(this).serialize());
      $.ajax({
      type: "POST",
      url: "your_some.php",
      data: data,
      }).done(function( msg ) {
      alert( "Data Saved: " + msg );
     });
});
