Adding a repeat input form post is this a syntax recognition issue in Wappler?

I am adding in repeat form input and I assume based on the examples given this is correct.

<div class="form-row" is="dmx-repeat" id="repeat_segments" dmx-bind:repeat="Segments.data"> <input id="segment_data" name="" class="form-control" dmx-bind:name="repeat_segments[{{$index}}][segment]" dmx-bind:value="segment">

However it appears wappler does not like this: repeat_segments[{{$index}}][segment]

Is there something wrong with my syntax or is it Wappler not liking it?
