Solution 1:

add a class or ID to the form tag.

echo elgg_view_form('submission_form', array('class' => 'elgg-form-submission_form'), array());

then in your JS file

$(".elgg-form-submission_form").submit(function( event ) {
    $.post("service_comments/add_service_comment", $(this).serialize(), function(result) {

}
