Delete from Laravel Database using button

Im trying to delete rows from an sqlite database and then refresh the page. This should all happen when i click the button(shown bellow).

Button:

<button type="button" class="btn btn-danger" onclick= "{{{ url("delete_item_action/$post->Id") }}}">Delete</button>

Here are the functions that should execute the sql query delete:

function delete_Post($id)
{
 $sql = "delete FROM Post WHERE id = ?";
 DB::delete($sql, array($id));
} 
function delete_item_action($id)
{
  delete_Post($id);
  return View::make('social.home');
}
