javascript - Ember, observers trigger in a strange order -

-

here's controller eventtimezonecontroller. content property set event model.

app.challengetimezonecontroller = ember.objectcontroller.extend     timezones: [{value: "", label: ""}, {...}]      timezonedidchange: (->         console.log "in controller", @get("timezone")     ).observes("timezone") # tried "content.timezone"

and event model:

app.event = app.challenge = ds.model.extend(ember.validations,     timezone: ds.attr('string')      timezonedidchange: (->         console.log "in model", @get("timezone")     ).observes("timezone") )

and then, have timezoneselect view

app.timezoneselect = ember.select.extend   valuebinding: "controller.timezone"   contentbinding: "controller.timezones"   optionvaluepath: "content.value",   optionlabelpath: "content.label"

now here's problem: when select new value in select dropdown, log shows:

> in controller american samoa > in model american samoa

why method timezonedidchange controller called before 1 in model, since understand, it's observing property of model?

in ember.js, controllers meant proxy model, makes sense call computed properties function on controller first. reference can check out informative talk luke melia @ ember.js nyc at min 31:30 slide shown concept.

hope helps
