I am receiving the following ADA Compliance errors, when running a page scan for WCAG 2.1 AA:

Buttons must have discernible text: button.rcbActionButton

<button class="rcbActionButton" tabindex="-1" type="button">select</button>

Form elements must have labels: input.rcbInput.radPreventDecorate

<input name="ctl00$MainContent$MyCombo" type="text" class="rcbInput radPreventDecorate rcbEmptyMessage" id="ctl00_MainContent_MyCombo_Input" value="Search..." autocomplete="off"></input>

This is the component:

 <telerik:RadComboBox ID="MyCombo" runat="server" RenderMode="Lightweight"
     EmptyMessage="Search..."
     AllowCustomText="true"
     MarkFirstMatch="true"
     Skin="Bootstrap"
     AutoPostBack="true"
     SelectMethod="GetInfo"
     DataValueField="Id"
     DataTextField="Name"
     OnSelectedIndexChanged="MyCombo_SelectedIndexChanged"
     MaxHeight="250px" aria-labelledby="InfoLabel" />
