title: jquery change attribute of icheck plugin
body: <p>I have this code to style a checkbox using the iCheck plugin for jquery, is there a way to change the 'insert' attribute later?. I tried recreating the iCheck but the callback function is deleted if I do it that way.</p>
  
  <pre class="lang-js prettyprint-override"><code>$(this).iCheck({
      checkboxClass: checkboxClass,
      insert: '&lt;div class="icheck_line-icon"&gt;&lt;/div&gt;' + $(this).attr("data-label")
  });
  
  $(this).on({ifChecked: function(){
      iCheckChange(this, yes);
  },ifUnchecked: function(){
      iCheckChange(this, no);
  }
  });
  </code></pre>
