Updating template with session variable and subscription/publication only updates with previous query and appends information

Question

How it works

I saw in my projects that, when subscribing/calling something on meteor, sometimes it run next code lines without having received previews server answer, and it bring some problems like yours. So, I usually nest what should be done inside the subscribe/call function, then it is run only after data is returned.

I would do something like this:

Template.List.events({
    'change #categories':function(evt){

         Meteor.subscribe("videos-pub-sub", $(evt.target).val(), function(){
               //to empty the table
               $('#video_table').find('tbody').empty();
               var vids = Videos.find({}).fetch();
               Session.set("videos-session", Videos.find({}).fetch());
         });

     }
});

Let me know if it works!
