column sorting for ag-grid not working

Question

I have an ag-grid and I am dynamically loading data into it. I have enabled column sorting, however it does not work. Nothing happens when I click on the column header. I'm not sure what the issue is. Below is my code:

    var colobj = {};
    for(i = 0; i< file.fieldMetadata.length; i++){

   var len = file.fieldMetadata[i].name.length;

   colobj = {'headerName' : file.fieldMetadata[i].name, 'field' : file.fieldMetadata[i].name, sortingOrder: ['asc','desc', 'null']};

vm.columnDefs.push(colobj);

    vm.gridOptions.api.setColumnDefs(vm.columnDefs);
    vm.gridOptions.api.setRowData(vm.fileContentsCols);
    vm.gridOptions.enableSorting = true;

Answer 1

The enableSorting won't work here. Only call to api function will work.

You have to set gridOptions.enableSorting = true from the beginning (not after receive the data).

The gridOptions is merely a holder for initialisation. Once the grid is initialise, the api field is available to interact with the grid, all change to parameters won't work.
