How to call quickui function in another plugin?

[xfyuan]

I'm writing a little plugin and try to call quickui#textbox#open in my own plugin, but it doesn't popup the textbox window. Could you give some example?

This is the demo code in my plugin:

    let l:result = "These are demo content!!"
    let x = substitute(l:result, '[\n\r]\+\%$', '', 'g')
    let content = filter(split(x, "\n"), 'v:key != ""')
    let opts = {"close":"button", "title":"Notes"}
    call quickui#textbox#open(content, opts)
