Datatable .Parse() method

Hi,
I tried to populate the table with data from db through parse but, when it runs from the second parse onward, it populates the table, but it does not show anything on the screen

be sure to use clearAll before parse, to delete the old data

table.clearAll();
table.parse(newData);

Without clearAll new data will be added to the end of the existing dataset.

Thanks, but the datatable is not populated.
