Well it does seem to [override alert](http://jsfiddle.net/tilwinjoy/tm78x12k/). Can you reproduce the issue..? — T J, Aug 12 '14 at 05:39

Your code for overriding the default alert function, contains another alert function bootbox.alert(str); due to which it goes into infinite loop showing too much recursion error. You could try below proxy pattern for overriding.

(function(event) {

  var proxied = window.alert;
  window.alert = function(str) {
   //Your code here
   proxied.apply(this, arguments);
   return true;
  };
})();
