IMPORTANT: it is important to load javascript data before loading jQuery.
 +
Because when jQuery is loaded it starts running and as soon as DOM is read, "handler" is
 +
called. When loading data file after jQuery, then jQuery may be faster to call handler, but
 +
without any data.

/* https://api.jquery.com/jquery.noconflict/

If for some reason two versions of jQuery are loaded (which is not recommended), calling $.noConflict(true) from the second version will return the globally scoped jQuery variables to those of the first version. Some times it could be issue with older version (or not stable) of JQuery files.

Solution: move new jQuery completely in new object and use this.
