I'm new to rails, and just found the simple\_form gem.
I installed it with bootstrap suport, but now I can't get this code to work the way I want it

```
<%= f.button :submit, "<i class='icon-ok icon-white'></i> Save", class: "btn btn-primary" %>

```

I just want to put the icon inside the button, but when I do this, it shows me a button with the text '<i class='icon-ok icon-white'></i> Save'

I also tried to do

```
<%= f.button :submit, class: "btn btn-primary" do %><i class="icon-ok icon-white"></i> Save<% end %>

```

But with no success. How can I add some HTML inside the button with simple\_form gem?
