Meteor remove blaze template in autorun

Question

I have a loading template. need to load loading template whenever client subscribe data from the server.

Template.myTemplate.onCreated(function() {
    var loading;
    Template.instance().autorun(function() {
         if (!Template.instance().subscriptionsReady()) {
           loading = Blaze.render(Template.loading, document.getElementsByTagName('body')[0]);
         } else {
           Blaze.remove(loading);
         }
    });
});

1st time Blaze.render and Blaze.remove works fine. But again if i do more subscription, It keep on adding loading template. How do I remove template from the DOM when else part executes?

Answer 1

if (!Template.instance().subscriptionsReady()) {
    if (Template.loading.isRendered) {
        return;
    }
    // if not rendered to DOM, then do render
} else {
    Blaze.remove(loading);
}
