Jquery Migrate says "isFunction" is deprecated

[deadlydud]

line 29
var setExpr = $.isFunction( document.createElement('div').style.setExpression );

if changed to:
var setExpr = document.createElement('div').style.setExpression;

then jquery migrate 3.4.x no longer complains about the isFunction being deprecated.

also:
line 554 and 556, change .bind( to .on( and .unbind( to .off( seems to make jQueryMigrate happy
