Template slot not working in oj-table

Summary:

Template slot inside oj-table not working properly.

Content (required):

I have an oj-table inside which there are many columns. The data source for this table is a BO in VBCS which is tied to a table in our ATP DB.

I have created templates for 2 columns - Transaction Date and Expenditure Item Date in which we are defining a date format to be displayed. Transaction Date is of type VARCHAR and Expenditure Item Date is of type DATE in our DB.

Below are the template codes.

    <template slot="Transaction Date">
      <oj-input-date value="{{ $current.data }}" readonly="true"
        converter='{"type": "datetime", "options": {"pattern":"MM/dd/yyyy"}}'></oj-input-date>
    </template> 
    <template slot="Expenditure Item Date">
      <oj-input-date value="{{ $current.data }}" readonly="true"
        converter='{"type": "datetime", "options": {"pattern":"MM/dd/yyyy"}}'></oj-input-date>
    </template>
