Duplicate bootgrid header and footer

Good afternoon! I use bootgrid to mount a table and an error started to occur.

Error: Once the table is loaded (the correct way, with the search bar and in the footer we have the navigation bar between pages), after a short interval (never standardized), the search and paging bars are duplicated.

Note:Thepagingbarthatappearsnextreferstotheamountofregistrationpresentedatthattime,soitalwaysappearswith1page.

Code:

varhtml='<tableid="grid-data" class="table table-hover table-striped tablerecords tabelas" >'+
                    '<thead>'+
                    '<tr>' +
