title: Mysql-events is not notifying the updated changes
body: <p>Here the code which I am using for auto notifying if there is any change in mySql database to nodeJS, it dosn't notifying?, at the same time I have edited my.cnf file also</p>
  
  <p>#my.cnf file</p>
  
  <pre><code>    binlog_format = row
      log_bin         = /var/log/mysql/mysql-bin.log
      binlog_do_db     = test   # Optional, limit which databases to log
  </code></pre>
  
  <p>Node JS</p>
  
  <pre><code>var MySQLEvents = require('mysql-events');
  var dsn = {
    host:     'localhost',
    user:     'root',
    password: 'root',
  };
  
  var mysqlEventWatcher = MySQLEvents(dsn);
  //console.log(mysqlEventWatcher);
  
  var watcher = mysqlEventWatcher.add(
    'test.eventTable',
  // test - database name, eventTable - table name
    function (oldRow, newRow) {
       //row inserted 
       console.log(oldRow);
       console.log('************');
       console.log(newRow);
       console.log('************');
      if (oldRow === null) {
        //insert code goes here 
      }
  
       //row deleted 
      if (newRow === null) {
        //delete code goes here 
      }
  
       //row updated 
      if (oldRow !== null &amp;&amp; newRow !== null) {
        //update code goes here 
      }
    }, 
    'Active'
  );
  </code></pre>
  
  <p>and i checked if my connection is established or not from node side like <code>console.log(mysqlEventWatcher);</code>
  it responds like </p>
