I have a button in my html:

<button id="confirm-download" onclick="submit(getStudentsDetails)" data-dismiss="modal" class="btn btn-success">Confirm</button>

and these are the submit and getStudentsDetails functions

function submit(callback) {
    $('#download_resumes').attr('action', '/api/studentsdetails/');
    $('#download_resumes').submit();
    callback()
}

function getStudentsDetails() {
    $('#download_resumes').attr('action', '/api/studentsdetails/');
    $('#download_resumes').submit();
}

Now these functions are referring to this form:

<form  id = "download_resumes" action="api/" method = "POST">

The problem here is that, only the second api (/api/studentsdetails/) is getting called here. I want both of these apis to be called onClick of the button.

The 2 APIs that need to be called are '/api/resumes/', '/api/studentsdetails/'.

Use Handler of submit and then call your second function like the following

function submit(callback) {
    $('#download_resumes').attr('action', '/api/studentsdetails/');
    $('#download_resumes').submit(function( event ) {
  alert( "Handler for .submit() called." );
  callback()
});
}

function getStudentsDetails() {
    $('#download_resumes').attr('action', '/api/studentsdetails/');
    $('#download_resumes').submit();
}

you can use ajax request to submit form and on success you can call that callback method

function submit(callback) {
//assuming callback is method name you want to call 
    $.ajax({
        url:'/api/studentsdetails/',
        data:$('#download_resumes').serialize(),
        success:function(response){
            window[callback]();
        }
    });        
}

window[callback] (); will call your callbackmethod on success refer this link for more information.
