Thoughts...
This demo only does a text input box at this time. You should be able to easily adapt this to include other means of input by passing an additional property in the JSON payload used to open the dialog (e.g. {"title":"Enter your age", "label":"Age", "type": "number", "min":1, "max":999 } that would hide the text box and instead show a number input spinner)
