My component is not usable in contribute mode

Here is my definition. It works fine on edit mode but I'm not able to use it in contribute mode.; this component not listed in the components list to use in contribute mode (to a dedicated area). What's wrong with it?

[jnt:myContent] > jnt:content, jmix:basicContent, mix:title
 - text (string)

and the related view jnt_myContent/html/myContent.jsp

<h2>${currentNode.properties['jcr:title'].string}</h2>
${currentNode.properties['text'].string}
