javascript - How to observe on properties and clear them on reload -

i'm reloading data view every 4 seconds this

var app = ember.application.create({     ready: function() {         setinterval(function() {             app.quotes.find().reload         }, 4000);     } }); 

and i'm fetching value in view this:

    <blockquote>     {{#each model}}         <p>{{message}}</p>     {{/each}}     </blockquote> 

question

every 4 seconds new request fired off rest api grab new quote. however, new quote getting appended existing quotes. how can overwrite old quotes , display new, changed, value?

see ember model reloading in interval , possibly make minor change:

didload: function(){   var self = this;   setinterval(function() {     self.clear(); // <- clears out existing record     self.reload();   }, 4000); } 

it's bit odd me doing in ember.application object instead of array controller. there reason doing this?
