title: Get plugin object reference back from element on which plugin is applied
body: <p>Please consider following code. Here I have a jquery plugin <code>myPlugin</code> by using which I changed the ui of <code>#targetElement</code> </p>
  
  <pre><code>var myPluginVar = $('#targetElement').myPlugin();
  </code></pre>
  
  <p>I created a button and added a click event listener on it</p>
  
  <pre><code>$('#myButton').click(function(){
      // HERE I want reference of myPlugin back.
  }
  </code></pre>
  
  <p>Now on a button trigger I want to get back <code>myPlugin</code> object.
  I don't want to use <code>myPluginVar</code>. Is there any way to get reference of <code>myPlugin</code> using element on which plugin is applied.</p>
