Actually the old meaning of Durga Puja also changed in Bengal. Most of the puja committee represents their ability to spend money and power rather then their divinity to goddess Durga. 

The children from outside of Bengal, who ware not part of Durga puja in Bengal, never feel the actual test of Durga puja. As long as they become elder, they will find their happiness what they will get easily near by their hand. They will be habituated by the local culture and festival rather then a foreign festival (Durga Puja).
