[TINYMCE] How to force "save" in all instances

If you post your data using ajax, tinyMCE can not start trigger to save data on submit.

To fix that, before send, you can force save.

for(var i=0; i < tinyMCE.editors.length; i ++ ){
  if (tinyMCE.editors[i].initialized) {
     tinyMCE.editors[i].save();
     tinyMCE.editors[i].isNotDirty = 1;
  }
}
