        this.collection = new Complex_collection(); // This is collection
        _.bindAll(this, 'render');
    },      
    add : function() {
        alert("hello");
        var friend_name = $('#input').val();

    var Complex_collection = Backbone.Collection.extend({

    model: Complex_model

});})(this);

You should not create new instance of the same object in the initialize code, your code should look something like this :

(function(){ 
    this.complex_model = Backbone.Model.extend({        
        sync:function() {},
        validate:function() {},
        url:function() {},      
    });
})(this);

// View

(function(){
    var vw = view = function(){};
    FriendView = Backbone.View.extend({
        events :{
            'click #add-input' : 'add'
        },
        initialize: function(){
            this.friendslist = new FriendList(); // This is your collection right?
            _.bindAll(this, 'render');
        },      
        add : function() {
            var friend_name = $('#input').val();
            this.friendslist.add({ name : friend_name });
        },
        render : function(){
            $("#friends-list").append("<li>"+ model.get("name")+"</li>");
        },      
    });
})(this);

// Collection
(function(){    this.complex_collection = Backbone.Collection.extend({
    model : complex_model
});})(this);

// Your main app
var view = new FriendView();
