JavaScript Backbone view optimization

I'm using backbone js in my Project, I'm struck in a small confusion with views.

I'm having these 2 views. After writing them i am in a confusion whether i'm in right path or not. The reason for my doubt is that the code was looking almost the same except that the el in which the view is rendered and the template that is used in the view.

Will this type of code effect the performance?? can I optimize it ?

code:

Project.views.list = Backbone.View.extend({
    // The DOM Element associated with this view
    el: '.lists-section-content',
    itemView: function(x){
        return new Project.views.list(x);
    },
    // View constructor
    initialize: function(payload) {
        this.data = payload.data;
        this.colStr = payload.colStr;
        this.render();
    },
    events: {

    },
    render: function() {
        sb.renderXTemplate(this);
        return this;
    }
});
