Vim: call object method in a custom function

I'm using neovim with the deoplete autocompletion plugin. I don't like the auto-auto complete, so I am trying to get completion to work using <Tab>. As the docs suggest:

inoremap <silent><expr> <Tab>
    \ pumvisible() ? "\<C-n>" : deoplete#manual_complete()

This works great ... except that <Tab> does not indent anymore even if I am at the start of a line (or there is a space under the cursor). I've written a function (poorly) to get around this:

function! Smart_TabComplete()
    if pumvisible()
        return "^N"
    endif
    let line = getline('.')                         " current line

    let substr = strpart(line, -1, col('.')+1)      " from the start of the current
    " line to one character right
    " of the cursor
    let spaces = strpart(line, -1, col('.'))

    let substr = matchstr(substr, '[^ \t]*$')       " word till cursor
    let spaces = matchstr(spaces, '[^ \t]*$')
    if (strlen(substr)==0)                          " nothing to match on empty string
        return "        "
    endif
    if (strlen(spaces)==0)                          " nothing to match on empty string
        return "        "
    endif
    deoplete#manual_complete()
endfunction

I call this instead of deoplete#manual_complete() above. Seemingly this fixes the using <Tab> for indent problem, but now inside the function I always get:

Not an editor command: deoplete#manual_complete()

I'm not really sure what to do about this, and I even tried passing deoplete in as an argument to Smart_TabComplete, but it doesn't work.

Use the :call command to call a function.

call deoplete#manual_complete()

If you need to return the results of deoplete#manual_complete() then use :return:

return deoplete#manual_complete()

For more help see:

:h :call
:h :return
