data-modal-submit attribute fails when an input tag is used instead of a button tag

[CaMer0n]

Bug Description

The data-modal-submit attribute typically moves any submit button (with an id='etrigger-submit' ) out of the modal iframe window and into the modal footer. (as long as 'buttons-bar' container is used). However, it does not currently work on <input> submit buttons, only on <button> submit buttons.

How to Reproduce

Main page

<a href="admin_config.php?mode=main&action=custom" data-modal-submit="true">New Modal</a>

Modal Page:

echo "<div class='buttons-bar'>".$frm->submit('send','Send', ['id'=>'etrigger-submit'])."</div>";

Expected Behavior

The same behavior for both types of submit buttons.
