Edit table record is not showing up the original value for Single Select field.

Hello experts,

I've a page showing up table records and editable, for this one field below I wanted to have a list of values to be chosen when editing, but once i got into edit mode, the current value 'P2' disapears, any idea where it is wrong for below template code of this field?

<template slot="Destination">

          <oj-bind-if test='[[$current.mode === "navigation"]]'>

            <oj-bind-text value="[[ $current.data]]">

            </oj-bind-text>

          </oj-bind-if>

          <oj-bind-if test='[[$current.mode === "edit"]]'>

            <oj-select-single data="[[ $variables.destinationADP ]]"

              :id="[['oj-select-single  -1829646926-1-' + $current.key]]"

                item-text="destination" value="{{ $variables.currentRowBuffer.destination}}">

            </oj-select-single>

          </oj-bind-if>

        </template>

$variables.currentRowBuffer is assigned with current row value on before row edit event.
