1. He saw his future Son-in-Law in Sameer.
2. He must have thought that if he gave him the job then he will pay the extra STD bills of his house (due to Delhi to Ahmedabad calls)
3. He wants to learn Guitar from Sameer (free of cost)
4. He wants to take revenge on dadi ( Kesab use to steal his shirt , sweater for using as mop in Somani house as per Dadi's instruction.)
5.He wants to learn bike stunt from Sameer.
6.He must have thought that from now on Sameer will transmit his "Dil ki baat" to Naina through radio and hence STD bills of his house will be less.
7. Cvs told him to do so.
If you have any idea please add on...
