JQMIGRATE: jQuery.fn.click() event shorthand is deprecated
Cause: The .on() and .trigger() methods can set an event handler or generate an event for any event > type, and should be used instead of the shortcut methods. This message also applies to the other > event shorthands, including: blur, focus, focusin, focusout, resize, scroll, dblclick, mousedown, mouseup, mousemove, mouseover, mouseout, mouseenter, mouseleave, change, select, submit, keydown, keypress, keyup, and contextmenu.
Solution: Instead of .click(fn) use .on("click", fn). Instead of .click() use .trigger("click").
