How we can add attachment in editable table?

Hello Everyone,

I am adding the file picker component like this, but after selecting file from frontend, file select chain is not executing and there is no error in console also.

<template slot="attachment"> 

<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-file-picker on-oj-select="[[$listeners.filePickerSelect]]"></oj-file-picker>

</oj-bind-if>

</template>

Please provide your valuable suggestions on this.

Thank you so much.
