Creating custom user tab

I am using this code it create a new tab, but it isnt working:

/* add new tab called “Submit Blog” */

add_filter('um_account_page_default_tabs_hook', 'submit_tab_in_um', 100 );
function submit_tab_in_um( $tabs ) {
$tabs[800]['submit']['icon'] = 'um-faicon-trash-o';
$tabs[800]['submit']['title'] = 'Cancel Subscription';
$tabs[800]['submit']['custom'] = true;
return $tabs;
}

/* make our new tab hookable */

add_action('um_account_tab__submit', 'um_account_tab__submit');
function um_account_tab__cancel( $info ) {
global $ultimatemember;
extract( $info );

$output = $ultimatemember->account->get_tab_output('submit');
if ( $output ) { echo $output; }
}

/* Finally we add some content in the tab */

add_filter('um_account_content_hook_submit', 'um_account_content_hook_submit');
function um_account_content_hook_submit( $output ){
ob_start();
?>

<div class=”um-field”>
Something here...

</div>

<?php

$output .= ob_get_contents();
ob_end_clean();
return $output;
}

this is a new installation of UM no other settings have been changed.
