How do I apply jquery-ui to a Backbone.js view?
var ButtonView = Backbone.View.extend({
    el: $('#ButtonId'),
    initialize: function () {
        $(this.el.selector).button();
    }
});

var ButtonView = Backbone.View.extend({
    initialize: function () {
        this.el.button();
    }
});

$(function(){
    var myButton = new ButtonView({ el: $('#ButtonId') });
});

var ButtonView = Backbone.View.extend({
    el: '#ButtonId'
    initialize: function () {
        $(this.el).button();
    }
});

$(function(){
    var myButton = new ButtonView({ });
});

var ButtonView = Backbone.View.extend({

    initialize: function () {
        _.bindAll(this, "render");
    },

    render: function () {
        this.el.button();
        return this;
    }
});

$(function(){
    var myButton = new ButtonView({ el: $('#ButtonId') }).render();
});
