                    this.set({height:getHeight}); //i am changing the height...
                    this.bind('change:height',function(){

Set the value after the binding if you want to monitor the event:

var Person = Backbone.Model.extend({
    initialize:function(){
        // bind is deprecated
        this.on('change:height',function(){
            console.log(this.get('height'));
        });

        var getHeight = prompt('provide your height');
        this.set({height:getHeight});
    },
    defaults:{
        name:'new Name',
        height:'unknown'
    }
});
