question how to support attributes with angulars 2 way binding support

Hi,

we are building some custom (native TS) web components that also support Angular 2 way binding on the value property
We added this to contributions\html\elements, auto complete works on html attributes and one way binding, but when [(value)] is set I get this warning: `Attribute [(value)] is not allowed here`. Anyone any idea what we are missing?


```JSON
{
"name": "ads-input",
"description": "A web component where a user can input text.",
"attributes": [
{
"name": "value",
"description": "Adds a value to the input field."
},
],
"events": [
{
"name": "valueChange",
"description": "Emitted when value changes"
}
],
"js": {
"properties": [
{
"name": "value",
"description": "Adds a value to the input field.",
"type": "string"
},
]
}
},
```
