numericTextBox allows to paste invalid values in strict mode


I have a numericTextBox as a field editor in my grid. 

<ej-grid id="Grid" 
        [editSettings]="{'allowEditing':'false', 'editMode':'batch', 'showConfirmDialog':false}"
                <e-column field="id" [visible]="false" [isPrimaryKey]="true"></e-column>
                <e-column field="duration" editType="numericedit" [editParams]="{'decimalPlaces': 2, 'minValue': 0}" headerTextAlign="center" headerText="Делал часов"></e-column>

The textbox works perfectly when user tries to manyally input the wrong values — values outside of min and max ranges, strings and other. However, if user copies the invalid value, and then pastes it into the field, then the numerictextbox does not prevent it. If for strings it simply returns NaN, it does not react for value outside of min-max ranges. Therefore, I have to validate the field manually, and that is not perfect, if there's easier ways.

Also concerning, that even though the field value is supposed to be numerical (int or float or other), the empty numeric text box returns empty string "" as a value. Again, it makes it neccessary to manually validate all the inputs.

I assume this is the problem of all textboxes, and not just numerical one. I have noticed similar behaviour on ej.datePicker.
