title: tinymce insert content - onclick
body: <p>Very new to tinymce and attempting a sizeable (for me) customization - tried a search, but not clear enough to know what I'm looking for... working with the code below (just showing top half), everything is working great, except I cannot get the Shortcodes items to insert at the cursor loc upon click - I have tried a number of variations but nothing has worked.  Is onclick still the appropriate method?  Any thoughts greatly appreciated.</p>
  
  <pre><code>TxtEdit = new tinymce.Editor(id, {
          inline: true,
          plugins: [
              "autolink lists link image charmap code insertdatetime table",
              "contextmenu paste textcolor colorpicker textpattern",
          ], 
          toolbar: "undo redo | styleselect | formatselect | pastetext | bold italic underline | alignleft aligncenter alignright | forecolor backcolor | bullist numlist | link | removeformat | fontselect fontsizeselect | code",
          menubar: false,
          paste_word_valid_elements: "b,strong,i,em,h1,h2",

          convert_urls : false,
          style_formats: [

                  {title: 'Name', onclick: function() {editor.insertContent('[st_user_name_style target= ]');}},
                  {title: 'Email', onclick: function() {editor.insertContent('[st_user_email_1_style target= ]');}}
              ]},
