Thx a lot... It seems that I made some mistake when isolating my code... Also on plunker, I saw some error when I dropped jquery which I need on my project)... Now I understand!
Not sure about scoping max, min, and stepSize... My goal was I to mabe them updatable/bindable from code or other binding (ex:switching AM/PM, max going from 12 to 24)
About requiring a ng-model, I'm not sure to see the benefit cause it's a bit new to me, but I see some example using that scheme.
Nice to have insightfull comment !

Got error on line 52 when clicking.
var input looks wrong to me as find does not work with class name : http://docs.angularjs.org/api/angular.element
Correction :
And maybe some optimizations :
