TextBlock Color change Dynamically - GoJs

Hi i am using gojs in my web application(ASP.Net MVC and Chrome browser) i need to provide text color change dynamically for Text Block.
I searched and found to use “stroke” keyword to change text color. but how to make this dynamically and choose color property by user.
I also checked Debug Inspector and Data Inspector. It is not available. “I need user to select text color for the block”

This Introduction page talks about how to do what I think you want: http://gojs.net/latest/intro/dataBinding.html

You can use an HTML Input of type “color” or use your preferred color picker. The DataInspector that we provide in the extensions does this.
