Robot framework: No keyword with name 'Wait Until Element Contains' found

From Robot framework documentation, I can see the keyword Wait Until Element Contains. I have the following keyword defined myself:

Wait for element content
    [Arguments]    ${elementti}    ${teksti}
    Wait Until Element Is Visible    ${elementti}
    Wait Until Element Contains    ${elementti}    ${teksti}

However, the following error is throw

No keyword with name 'Wait Until Element Contains' found. Did you mean:
    Selenium2Library.Wait Until Title Not Contains

I'm using robotframework-maven-plugin 1.4.6
