javascript - How to avoid template wrapping with empty div in Backbone?

When I create view backbone creates empty div-container if el is not set. Template (this.$el.html(this.template(this.model.toJSON()))) inserted in that div. How to avoid this wrapper? I need clean template without any wrappers so I can insert it anywhere I want? It's not reasonable to call jobView.$e.children() with many elements.

<script id="contactTemplate" type="text/html">
                <div class="job">
                    <h1><%= title %>/<%= type %></h1>
                    <div><%= description %></div>
                </div>     
</script>     

var JobView = Backbone.View.extend({
        template:_.template($("#contactTemplate").html()),

        initialize:function () {
            this.render();
        },
        render:function () {
            this.$el.html(this.template(this.model.toJSON()));
            return this;
        }
});

var jobView = new JobView({
   model:jobModel
});          

console.log(jobView.el);

I think the real answer to this question has not been provided yet, simply remove the div from the template and add the className property to JobView! This will result in the markup you require:

The template:

<script id="contactTemplate" type="text/html">
     <h1><%= title %>/<%= type %></h1>
     <div><%= description %></div>
</script>

The view:

var JobView = Backbone.View.extend({
            className: 'job', // this class will be added to the wrapping div when you render the view

            template:_.template($("#contactTemplate").html()),

            initialize:function () {
                this.render();
            },
            render:function () {
                this.$el.html(this.template(this.model.toJSON()));
                return this;
            }
    });

When you call render you will end up with the desired markup:

<div class="job">
  <h1><%= title %>/<%= type %></h1>
  <div><%= description %></div>
</div>
