jQuery duplicating ASP.NET button value

jQuery duplicating ASP.NET button value

I currently have a working Web App built with ASP.NET that I'm now implementing a page slide transition for. I have done this successfully but with one issue.

It seems jQuery is duplicating the button value when the page is rendered.

<input name="Submit input" data-type="button" type="submit" value="Login & Connect" />

So when the page is viewed, My button shows with the correctly styled "Login & Connect" with an additional "Login & Connect" also being placed inside the button.

If i remove jQuery or jQuery Mobile this issue goes away but obviously page transitions no longer work.

Many thanks.
