How to refresh a model after a request to API

enter code here
actions:{
    deleteWorklog: function( worklogId ){
          var model = this.get('model.logs');
          var data = { auth_token: this.get('local_data').user_token };
          Ember.$.ajax({
               method: "DELETE",
               url: this.get('url') + "/" + worklogId,
               headers: { 'X-Api-Token': data.auth_token }
          }).then(function(data){
             //how do i do it?
          })
    }
}

I'm blocked after the request, i need to refresh my model but i've to do cmd + R to see the change, is there a method re-call the model or something like that?

Thank you for your time!
