jquery - Grails jquery post only working with an alert present?

Question

So, I've got a link on a page which calls a little jQuery function, which in turn posts to a controller, the controller just runs some SQL before refreshing the page.

All this works nicely, while debugging it with lots of alerts etc to make sure things are doing what I want. BUT, once I remove all the alerts it stops working?! Any ideas? You can see the commented out alert in the function below, commented out nothing happens, no SQL update, nothing. If I add that alert back in it then works fine?!

Has anyone ever come across this or found a way around it? Is there a way/obvious reason why this is happening? Cheers!

jQuery function

function reQueueTest(url, id){
    $.post(url, { id:id },function(data){   
    });
    //alert("work!")
    location.reload(true);
}

Controller

def reQueueTest(int id){
    def sql = new Sql(dataSource)

    def rowID = id
    sql.executeUpdate "update test_exec_queue set [State]='READY' where test_exec_queue_id=$rowID"
    sql.close()
}

Edit:

Ok, so try to reload in the done method:

function reQueueTest(url, id){
    $.post(url, { id:id },function(data){   
        }).done(function() { location.reload(true); })
          .fail(function() { alert("error"); })
}
