Will I require a visas while travelling through Kualalampur, from Singapore to Dhaka by Air Asia.?

I am from Bangladesh.From the Malaysian Mission here we are allowed a Single entry visit visas only. I will be travelling to Kualalampur, stay 9 days then take an Air Asia flt to Singapore and return to Kualalampur after 3 days and depart for Dhaka,Bangladesh the same day, by Air Asia without coming out of the Airport. Will I require a second port entry visas to Malaysia in doing so. Thanks in advance. Regards.
