There is an even nicer way to handle this if your model includes lots of properties in it.

SampleView = Backbone.View.extend({
    el: "#formEl",

    events: {
        "change input": "changed",
        "change select": "changed"
    },

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

    changed:function (evt) {
       var changed = evt.currentTarget;
       var value = $(evt.currentTarget).val();
       var obj = {};
       obj[changed.id] = value;
       this.model.set(obj);
    }
 });

There is a reliance on your input elements having an id the same as the what the name of the property in your model is.
