I am having a form which will submit list of products to the spring backend

I have two separate buttons 1). Submit button to submit the form 2). Fetch available Stock button to check stock availability

When i click Fetch available stock button -- it will invoke a function which will make Ajax call to fetch stock details

But the problem is whenever i click Fetch available stock button

Both ajax call for fetching stock data and form submission also happens.

I don't want the form to submit till i press the submit button

Note: i am having the form in bootstrap modal

Thanks in advance for helping me!
