7		}
8	});
9
10	Meteor.methods({
11		search: function(query, options) {
12			options = options || {};
13
14			// guard against client-side DOS: hard limit to 50
15			if (options.limit) {
16				options.limit = Math.min(50, Math.abs(options.limit));
17			} else {
18				options.limit = 50;
19			}

31        if (err) {
32          console.log(err);
33          return;
34        }
35        callback(res.map(function(v){ return {value: v.name}; }));
36      });
37    }
38  });
39}

Initializing the typeahead

When the DOM is loaded through Meteor.startup on each template

1Meteor.startup(function() {
2  Meteor.typeahead.inject();
3});

with iron:router

Using iron:router the Meteor.startup is already triggered because it loads the template or the loading template and then inject the data. It must be delayed to when iron:router knows it is rendered completely.

1Template.demo.rendered = function() {
2  Meteor.typeahead.inject();
3};
