I need to use 'data-binding-disabled' with 'Conditional' 'does not Contain'.

Usage is when I need an input to contain specific characters or words to enable the Submit button.

Perhaps there should be something like 'data-binding-enabled' or 'Conditional' 'does not Contain'?

Or did I miss something? I can achieve what I want with 'data-binding-show' but I just want to disable the button not to hide it.

Hello Firdaus,
This requires a little bit of custom coding.
First, include this in your head tags, after the HTML5 Data Bindings Formatter include:

<script>
function string(obj) {
 return obj + '';
}
$.extend($.dmxDataBindings.filters, {
 notContains : function(val, str) {
  return string(val).indexOf(str) == -1;
 }
});
</script>

Then this is the code you need to bind to the button:

data-binding-disabled="{{$FORM.yourFieldName.notContains( "enterWordHere" )}}"
