Property 'reset' does not exist on type 'baseview'. angular

I want to use webix with angular 6.
Getting the below error while using $$ in the below code.
$$(“ss1”).reset();
$$(“ss1”).parse(upload.file, “excel”);

error TS2339: Property ‘reset’ does not exist on type ‘baseview’.
error TS2339: Property ‘parse’ does not exist on type ‘baseview’.

Facing same issue for start() in webix-hint.

maybe you need clearAll
