traps:

when use button as the _button target of FileUploader, it will create a input[type=file] in the tag, which looks like this:
<button id="upload-button"> <input type="file" /></button>

now, if you attempt to use bootstrap's button text functionality, like this:
<button id="upload-button" data-loading-text="Loading"><input type="file" /><button>
$('#upload-button').button();

and when you change the text and change it back, the events binder to input[type=file] will be lost.
