jQuery Summernote – Get text back into editor

Since v0.7.0 code() has been deprecated and removed (same story for destroy() method).

You must use $(".summernote").summernote("code", "your text");

Reference: https://summernote.org/getting-started/#get–set-code

After v0.7.0, direct jquery methods, destroy and code were removed for avoiding conflict with other jquery libraries. You can call this methods with summernote api.
