Can we add a new control with in IconTabBar in SAPUI5

Hi,

I am new to SAPUI5.

Based on the documentation we must be able to add a new control as an Aggregation with in IconTabBar, but I am facing issues while adding.

I am trying to add a search filed beside icons with in IconTabBar, but some how it is throwing exceptions. Below code for reference.

<IconTabBar enableScrolling="true" expanded="true" expandable="false" id="idIconTabBar" >

  <items>

         <IconTabFilter icon="sap-icon://accept" iconColor="Neutral"  design="Horizontal" count="" />

               <IconTabSeparator icon="sap-icon://open-command-field" />

         <IconTabFilter icon="sap-icon://value-help" iconColor="Neutral" design="Horizontal" count="" />

         <SearchField width="90%" class="marginAll" />

  </items>

</IconTabBar>

Please assist.
