I am try to implements datatables filter inside polymer from this link https://jsfiddle.net/bindrid/2bkbx2y3/6/

But when I apply into polymer I found some issue when push to datatables a plugin method. in polymer I use vaadin-date-picker as datepicker, and here's my code :

  1. HTML 

    <template>
<form class="form-inline m-b">
    <div class="form-group form-group-sm">
        <vaadin-date-picker id="min" placeholder="Start"></vaadin-date-picker>
        <vaadin-date-picker id="max" placeholder="End"></vaadin-date-picker>
    </div>
</form>
<table id="mainTable" class="table table-condensed table-striped table-bordered" style="width: 100%">
    <thead>
        <tr>
            <th>STAD</th>
        </tr>
    </thead>
</table>

  2. Script :

    class DataTableD extends Polymer.Element {
    static get is() {
        return 'data-table-d';
    }

    ready() {
        super.ready();

        var min     = this.$.min;
        var max     = this.$.max;

        //push method into search
        $.fn.dataTable.ext.search.push(function (settings, data, dataIndex) {
            alert("min . ." + min) //min . .[object HTMLElement]
            var startDate = new Date(data[0].replace( /(\d{2})-(\d{2})-(\d{4})/, "$2/$1/$3"));
            if (min == null && max == null) {alert("startDate . ." + startDate);}
            if (min == null && startDate <= max) {alert("startDate . ." + startDate);}
            if (max == null && startDate >= min) {alert("startDate . ." + startDate);}
            if (startDate <= max && startDate >= min) {alert("startDate . ." + startDate);}

            return false;

        });
        // Event listener to the two range filtering inputs to redraw on                                
        min.addEventListener('value-changed', function() {
            window.setTimeout(function() {
                max.value = min.value;
                max.open();
            }, 500);

            this.$.mainTable.draw();
        });

    }

    _initializeDatatable() {
        if ( ! this.$mainTable) {
            // Make the jQuery object of the mainForm and arrivalTable.
            this.$mainTable = $(this.$.mainTable);
        }

        this._dataTable = this.$mainTable.DataTable({
        });
    }
}
window.customElements.define(DataTableD.is, DataTableD);

hope someone can share the idea to make it works, thx

Here below I tried to illustrate another way to filter :

DEMO

HTMLImports.whenReady( ()=> {
  
class DataTableD extends Polymer.Element {
    static get is() {
        return 'data-table-d';
    }
    static get properties() {
       return {
          minDate:{type:String },
          maxDate:{type:String }
    }}
    static get observers(){
       return ['_checkMinMaxDate(minDate, maxDate)']
    }
    ready() {
        super.ready();
    }


  _checkMinMaxDate(min,max) {
    console.log("Min-max:", min,max, this.items, this.xitems);
    var minn = min==="" ? "1000/01/01":min;
    var maxx = max==="" ? "2050/01/01":max;
    var newItems =  this.items.filter( (el)=> {
         return el.Startdate <= maxx &&
         el.Startdate >= minn ;
});
    this.set('xitems', newItems);
    
  }
}
window.customElements.define(DataTableD.is, DataTableD)

})

EDIT

How to pass data outside Polymer

_checkMinMaxDate(min,max) {

    this.dispatchEvent(new CustomEvent('date-changed', { bubbles: true, composed: true, detail: {items:this.items, startDate:min, endDate:max }}));
}

outside of the Polymer: 

window.addEventListener('date-changed', (e)=> { 
     console.log(e.detail.items) // your items 
     console.log(e.detail.startDate) // Date to start 
     console.log(e.detail.endDate) // Date to end.
})
