I got a solution, its related to a Javascript binding problem. The problem is, when you delete a product from the cart all the cart block gets updated. Hence it removes the already bound javascript.

I have added the javascript bind code at the end of updateBlocks function in ajaxcart.js.

So, whenever user tries to delete a item from the cart ajax code gets executed and the response update_blocks will once again gets bind to the cart even after the initial javascript binding.

Added Javascript bind code is

$$('a[href*="/checkout/cart/delete/"]').each(function (e) {    
            $(e).observe('click', function (event) {    
                setLocation($(e).readAttribute('href'));    
                Event.stop(event);    
            });    
        });

And after adding code to ajaxcart.js updateBlocks function look like ,

updateBlocks: function (blocks) {    
        var _this = this;
        if (blocks) {    
            try {    
                blocks.each(function (block) {    
                    if (block.key) {    
                        var dom_selector = block.key;    
                        if ($$(dom_selector)) {    
                            jQuery(block.key, parent.document).each(function (e) {    
                                jQuery(this).html(block.value);    
                            });    
                        }    
                    }    
                });    
                _this.bindEvents();    
                _this.bindNewEvents();    
                // show details tooltip    
                truncateOptions();    
            } catch (e) {    
                console.log(e);    
            }    
        }    
        $$('a[href*="/checkout/cart/delete/"]').each(function (e) {    
            $(e).observe('click', function (event) {    
                setLocation($(e).readAttribute('href'));    
                Event.stop(event);    
            });    
        });    
    }
