validation - Emberjs Autocomplete updates another one -

i have 2 autocomplete fields , need update second autocomplete list first selection. have.

using jquery.mixin , validation.mixin input boxes.

ng.createinsertblncontroller = ember.objectcontroller.extend(ng.validate,{ content: [] }   ng.createinsertblnview = ember.view.extend({   vesselpicker: jq.autocomplete.extend({    source: ng.vessels.autocomplete,    minlength: 0  }),   voyagepicker: jq.autocomplete.extend({        // jq.autocomplete extends ember.textfield   source: ng.voyage.autocomplete,   minlength: 0  })  });  ng.vessels = ember.objectcontroller.create({  inputtext: "",  autocomplete: function(request, response) {    var term = request.term;    var self=this;     $.getjson( "http://myjsonlink", request, function( data, status, xhr ) {          var list = [];         $.each(data,function(id,item){             list.push(item.code);         });         response( list );     }); } });   ng.voyages = ember.objectcontroller.create({  inputtext: "",  autocomplete: function(request, response) {    var term = request.term;    var self=this;     $.getjson( "http://myjsonlink", request, function( data, status, xhr ) {          var list = [];         $.each(data,function(id,item){             list.push(item.code);         });         response( list );     }); } });
