Javascript error - Object has no method

Question

I got the following script shortened :

var HTH = HTH || {};

(function() {
    var assetGrouping = function() {
        var self = this;

        this.options = {
            _tmpElement:        '',
            QuantityAssigned:   0,
            qtyInputField:      ''
        };

        this.init = function(options){
            // ...
            this.options.QuantityAssigned = 0;
            jQuery(this.options.qtyInputField).bind('keyup', function(){
                self._tmpElement = jQuery(this);
                self.CalculateQuantityAssigned();
            });

            // ...
        }

        CalculateQuantityAssigned = function(){
            // ...
        }
    }

    HTH.assetGrouping = new assetGrouping();
})();

$(document).ready(function(){
    HTH.assetGrouping.init({
        qtyInputField: 'input[name^="at700_group_qty"]'
    });
});

The error happen at the following line : self.CalculateQuantityAssigned(); and the error is Uncaught TypeError: Object [object Object] has no method 'CalculateQuantityAssigned'.

I don't understand. Using this will fail of course and self is working when I want to access self.options but not for self.CalculateQuantityAssigned().

Thanks.

this.CalculateQuantityAssigned

Change:

CalculateQuantityAssigned = function(){
            // ...
}

to

this.CalculateQuantityAssigned = function(){
            // ...
}

(function () {
});  <-- You have a function, but you never execute it!

You need to add the ();

You are right, })();. It is there, just my mitake that I didn't put in the "demo" script above.
