json - Meteor.http.call (call URL API) -


so i'm trying make call bible verse api in meteor application. made template name="display", simple {{checkitout}} in template.

then template, tried make call in corresponding helper. looks (in coffeescript, javascript readers should understand well): 

@template.display.helpers     checkitout:->         result = meteor.http.call("get","http://labs.bible.org/api/passage=john%203:2&type=json")         console.log(result)

the url json of bible verse, problem is, meteor.http.call requires third argument, "callback" (because in client folder). read documentation + examples , have no idea means.

also, if call this, result json file, or need fit within new hash? , callback mean? can give me example?

as helpers synchronous , api calls not, need store call result in reactive variable , return helper:

verse       = "loading..." verseloaded = false versedep    = new deps.dependency()  template.display.checkitout = ->   versedep.depend()   unless verseloaded     verseloaded = true     meteor.http.get "...", (error, result) ->       verse = "..."       versedep.changed()   verse
