How to select a row in rich:dataTable by mouse click?

I have a rich:dataTable on one modalPanel alongwith two commandButtons named as OK and cancel. In one of the columns I have radio buttons. By selecting a radio button and then click OK. I am able to select that particular row. But my requirement is to delete the column which has radio button. I want to select the row by clicking on it and then OK. If user clicks on a row and does not want to select it then simply clicks Cancel. Below is the piece of code which implements the functionality with radio button.

      <h:outputText  id="selectAlarmToEnrich" value="#{bundle.modal_panel_label}" styleClass="staticTextLabelStyle"/>
      <div class="dataTableSetting">
      <rich:dataTable id="AlarmListTable" value="#{aeAlarmNEList.alarmInfoDTOList}"
 var="alarmsInfoDto"
 headerClass="table"
 styleClass="tagTable"
 rowClasses="odd,even"
 onRowMouseOver="this.style.backgroundColor='#A9D0F5'"    
                onRowMouseOut="this.style.backgroundColor='#{a4jSkin.rowBackgroundColor}'"
 rows="#{aeAlarmNEList.selectedRecordsPerPageCount}">

  <rich:column id="alarmId">

   value="#{alarmsInfoDto.alarmId}" />

Consider associating radiobutton with identifier of the data in the row.
