(1) HAL Tejas is not yet combat-ready, and, God knows when it would be.
Don't bother to ask God or Allah, it will be combat ready from the Day 1 of FOC
(2) JF-17 is going through its Block-III development phase. Once, the development is complete, it would achieve significant improvement in terms of performance and capability. Better engines, better avionics, better radar, and so on. Just imagine a JF-17 with Saturn AL-31 engine, and, Phazotron Zhuk AE AESA Radar!!!
Better Engine -- Which one AL-31 are you kidding, it will mean to change the whole fuselarge, whole airframe, flight data and whole test in another word to develop another new plane, better would be to buy J-10 with Saturn AL-31 engine
Better Avionics -- Who is stopping you to buy for JF-17 from the Itallion or BEL/CASSIDIAN but its the PAF and the officials who are satisfied with the Chinese.
Better Radar -- Phazotron Zhuk AE AESA Radar is available for India from 2007, question is does is it available for the PAF or Chinese, but don't worry the KLJ-7 Radar is nothing but the Zhuk Pulse doppler radar, with Chinese Antenna.
