Hi Niloy,
As i read through the datasheet (page 13), I found out the error in your circuit is the value for feedback resistor. 1kohm is recommended as feedback rather than 10kohm.

Clik here to view.
In your case, you can change your RF value to 1kohm and your RG to 1.2105kohm (1.21kohm as nearest standard value). I already tried it and its working fine.

I hope this helps.
