Reuse your render method to be standardised

by-call.js

myNameSpace.backboneExtensions.methods.render = function() {
  this.$el.html(this.tmpl(this.model.attributes));
  return this;
}

MyView = Backbone.View((function() {
  var myRender = myNameSpace.backboneExtensions.methods.render;
  
  return {
    // your properties
    
    // render
    render: this.call(myRender)
  }
})());

by-extend.js

MyApp.BackBone.View = Backbone.View.extend({
  render: function() {
    this.$el.html(this.tmpl(this.model.attributes));
    return this;
  }
});

ExampleView = MyApp.BackBone.View.extend({
  el: 'li'
}); // this Backbone view's render method automatically renders whatever is in the template
