[jQuery] Delay function to wait for post

[aeg1s]

I have the following code:

$('#r_0_0').blur(function() {

 var x = $('#r_0_0').val();
  var y="#d_0";
  $(y).empty();
  $.get("apps/P5001/call/LineItems.lasso?LITM=" + x + "&Line=" +
'r_0_0' + "&TEST=" + y,function(data2){
  $(y).empty();
  $(y).append(data2);
  },"html");

  $('#addnew').click();

});

The last line "#addnew" is adding a new line to a html table, and the
other code is updating a div with information from a database call. It
is all processing correctly, except the "addnew" is running before the
database query.

How can I get the "addnew" to wait for the prior commands to finish?
