A detailed description of working with JET elements and classes in your typescript project can be found at:
JET Typescript Usage.
Use <oj-bind-text> to generate a text node with the resolved expression. Note that the
<oj-bind-text> element will be removed from the DOM after binding is
applied, and any child elements it has will be removed. For slotting, applications
need to wrap the oj-bind-text element inside another HTML element (e.g. <span>) with the slot attribute.
The oj-bind-text element does not support the slot attribute.
