bug(datepicker): doesn't fire ng-change events

[ostronom]

I have an issue with ng-change and datepicker directive. In this piece of code:

<...ng-repeat="p in props"...>
   <div datepicker ng-model="p.value" ng-change="myScopeFunction()"></div>
<...>

myScopeFunction is never called.

Oh, I see... @bekos we should probably consider plugging into the NgModelController instead of binding directly to the model The advantage of the NgModelController is that we can plug into the existing parsing / formatting pipelines and have validation etc.

@pkozlowski-opensource I agree that this would be the best practice, but I am not sure how this could work with an isolated scope. I will look into this.

@pkozlowski-opensource There is an open issue for isolated-scope and ngmodelcontroller in AngularJS, so I don't think we can do many things atm.

Probably, a solution is to add a onSelect callback to let the user hook to the date selection, rather than watching the model for changes. WDYT?

@bekos was just updating this issue :-) So, there is no real "issue" of isolated scopes and ngModel - it is just that in the current version of AngularJS a given DOM element is associated with one and only one scope. I agree that this is a pain but there are ways out. In the typeahead directive I'm creating an isolated scope for popup matches and manually evaluate expressions against a proper scope.

I'm not saying that this is what we should be doing for the date-picker directive but we will have to find a solution if we want it to work with inputs. Plugging into ngModel will be necessary to support custom date formats.

Anyway, I agree that this is not a trivial topic, especially if we want to combine it with a popover. But hey, we are AngularJS masters, got AngularJS commiters in the team and can ask for help from the core team. So I'm sure that we will find a good solution!

I would be really keen on seeing datapicker integrated with popovers / inputs and I can help with design issues / reviewing code etc. On my side I would like to finish $dialog rewrites. Also we should try to fix existing bugs as to prepare for AngularJS 1.2 / Bootstrap 3.0 migration.

@johntom Thanks, it worked for me (after debugging this for 3 hours)
@bekos You should update the documentation by this.
