Manmohan Desai Amitabh Bachchan

After giving such collosal hits like Chacha Bhatija,Dharam Veer,Bhai Ho Toh Aisa,Roti and Saccha Jhootha Why did Manmohan Desai never worked With the Likes of Dharmendra, Jeetendra and Rajesh Khanna ever again . Even if an actor director have problems during the making of a movie if the movie turns into a big hit they work again together best example Salman Khan and Kabir Khan after having issues during Ek Tha Tiger due to it's super success they worked again in Bajrangi Bhaijaan What did these actors lacked why Amitabh Bachchan had . Why didn't do they work any particular reason?
