how to reload hasMany relationship data in ember data 2.8

when first time calling model.get('list') its fetching record from server but second time its fetching from store but i want always response from server.

I am using

Ember js 2.8.3

Ember data 2.8.1

my model is like below

model:function()
{   
    var model = this.modelFor('view').get('list');
    if(model.get('content.isLoaded'))
    {
        return model.reload();
    }
    return model;
}

same model was working as i mention above in ember data 1.13.8

Thanks in advance for help.
